With the Classic beta now out it seems every related article somehow manages to spark the eternal war of "Vanilla was the best WoW sucks now" and "lol nostalgia goggles, Vanilla sucked, enjoy your two weeks of Classic". I have to say, even though I understand the principles behind the battle and the reasons people behave and talk this way... I actually REALLY don't get it on a deeper level.
When hovering over an ability, the tooltip will tell you whether or not that attack is weak or strong against certain pet types. Additionally, you can hover over the opposing team's pets and view their attacks during combat. This will be important since it’s a good idea to pit a pet that's strong against the opponent's pet who's vulnerable to that type.
The system is automated, meaning that once slots are available, beta testers will be chosen, without any beta key to speak of. Kaivax then goes to stress the importance of your account security, stating that, “any third-party e-mail messages, websites, or in-game whispers that offer beta keys or access to the WoW Classic Beta should be considered illegitimate and ignored or reported.”
Doomguard: The Doomguard serve as the Burning Legion’s lieutenants, captains, and generals. While it is incredibly unlikely that a demon hunter would be capable of defeating a Doomguard within their summoning circle, those that succeed would be granted overwhelming and overbearing power, the like that few would be able to contain. However, just as the Doomguard serve as the Burning Legion’s battlefield leadership, perhaps a sliver of that might be imbued within the handful of demon hunters capable of binding themselves with one and surviving.
To actually get access to the beta, which has already started and continue to add more players, you need to sign up via your Blizzard account management page. Under Games & Subscriptions, scroll down to Beta Access and visit the Beta Profile Settings page. Once there, you’ll see a grid of available betas you can opt into. Once you’ve checked WoW Classic, hit Update Preferences and you’re set.
Wrathguard: (Caution) The martial Eredar of the Burning Legion, these soldiers enact the will of the masters of their cause. Where the Felguard often charge crazed into battle, the Wrathguard operate under a singular purpose that is to protect their charges and to strike precisely against the enemies of the Burning Legion. Just the same, the Eredar Wrathguard are not to be trifled with, showcasing a pinnacle threat to any demon hunter unfortunate enough to summon one during their ritual. However, those that are capable of defeating these outstanding soldiers and maintaining their power would no doubt be imbued with the same physical endurance and threatening presence as that which now labors within them to escape.
Within the context of Classic, the method most frequently proposed is to re-tune bosses to make them harder. Rather than copying the numbers, re-create the relative difficulty. Kind of like, when you first start working out, you use small weights. When you get stronger, you lift bigger weights. The WoW community is more knowledgeable, more experienced, has better hardware, etc. We're "stronger." So give us tougher bosses. There are a lot of forms that could take. Bosses were constantly re-tuned during vanilla anyway, so if Ragnaros does 10% more damage or something, is that really a problem? I don't think it is. What about resistance gear? back in the day, collecting resist gear was a thing people did. But the numbers and strategies are so well known today that only the tank really needs it anymore. Bosses could be re-tuned with more resistible elemental damage so that's important for entire raids to gear appropriately. That would be entirely keeping with the spirit of vanilla even if the actually numbers sitting in a database somewhere were different than they were ~13 years ago. If you want to go a little farther, a few people have proposed adding new abilities to old bosses, adjusting their timing, etc.
Zygor was the home planet of the Zygons. (PROSE: The Bodysnatchers) It was known to be warmer than Earth and covered in water, which was in the form of lakes with a different mineral composition than those of Earth. There were also no icecaps on the planet. Native lifeforms of Zygor included the unaltered Skarasen and the Zygons. (TV: Terror of the Zygons)
Using the power of the cloud, we monitor every realms Auction House, even when you're not in-game, and process this data through our custom system developed together with gold experts. We then serve this data directly to you through the Zygor Guides Client, allowing you to gain months of Auction House analysis in seconds. What this means is that our gold guide can dynamically adapt to the unique marketplace conditions of every realm you play on. Best of all, this service is included as part of Zygor's Gold and Auctions Guide.

The closed beta for Blizzard’s upcoming World of Warcraft vanilla server option launched on May 15th, and Blizzard has now listed some of the apparent issues that the development team is aware of, including class and combat related issues alongside missing textures and more. Blizzard mentions that this list is not a complete depiction of what they’re aware of, but a sampling of issues they believe players may encounter on regular basis.

Analogy: think back on riding the swings in kindergarten. Was it fun? Now, imagine going back to those swings exactly as they were, and sitting in them now, as an adult. They're too small. They don't fit. Your feet drag on the ground because they're so low to the ground. The bar over your head is low enough that you can reach out and touch it, and even at the highest the swing will go, it's only about chest high when you're standing up. It's exactly the same swing, but riding on it now is a very different experience, yes?
Instead of sharding the zones, their plan is to shard the entire continent at launch. In Classic WoW, there are no dynamic spawns and questing in starting zones would quickly become annoying, so it's understandable that the game is all but fun when there are no mobs to kill, but layering will also cause you to see new players, every time you sign in to the game, which is a clear downside of the tech. 
No he's just not paying attention. The wanted quests are built into both the leveling guides and the "Zandalar Forever" achievement guide. They aren't in the rep guide because they are not repeatable and by the time you hit max level they should be done. You'll also notice the rep guide doesn't contain every single possible completable quest that rewards rep. It is designed to focus on repeatable objectives, world quests, large quest lines, and missions.
I have tried it a few times. It's good if you're new to the game. Otherwise not so much. I found I leveled slower by using it, as it's suggesting to take the longest possible route usually. Basically following roads everytime, when you could take an easy shortcut. Especially if the shortcut involves a bit of fall damage, it's out of question. The "go here" spots don't also update if you take a shortcut, and then the waypoint arrow points to wrong direction. But perhaps it has been updated since then.
In Classic, playing different classes actually feels different in more ways than just their abilities, at least if you think about it a little. Playing a priest, you really want to find a group because that's what the class was designed for, which is both good and bad - you're stuck very slowly leveling if you're solo, emphasizing the frustration of the slow pulling, but having different classes require different gameplay can be good. If you want to play a priest you're going to have to be more social by default, just whisper the guy you see killing stuff next to you and go level together, you'll immediately have a better time of it (this part is particularly exacerbated in the beta, as there are fewer players).
One thing they told me when I dabbled into computer science back at university was that 80% of the bugs only take 20% of your time to fix. That's why sometimes you see issues persisting for very long times, not because the devs are lazy or incompetent, but because there is usually a priority list of problems, with the severe-but-easy-to-fix ones always taking precedent and the not-game-breaking-but-difficult-to-solve problems being last line.

1 All expansion guides are written in the Battle for Azeroth beta in order to have them ready on launch day. It's important to note that betas can be buggy and unstable and may delay and even halt our progress on the guides. Furthermore, the time between the start of beta and the announced release of Battle for Azeroth is much shorter (by about 2-3 months) than past betas. As a result, our primary focus is to have the Leveling guides updated by the launch, and only if those are complete and time remains will we work on updating the remaining guides. All guides not finished in beta will be updated post launch. You can read more about this here.
Only really to expand on Gráinne's comment as regards the 'collecting' and 'roster development' sections - which are, as said 'distinct' although they are intrinsically linked - I would like to point you in the direction of the in-game Achievements > Battle Pets > Collect tab. There are a series of achievements called Raiding With Leashes, pretty much all of which can be completed via the auction house - if you have the gold/inclination - or by completing old raids.
Different qualities aren't limited only to wild pets—many rare World drops and special non-wild companions have had their stats boosted. For example, the world-drop dragon whelps (Azure Whelpling, Crimson Whelpling, Dark Whelpling, and Emerald Whelpling) are of [rare] quality. Check your Pet Journal to see the color-coded rarity of your non-wild pets.
“Vandel fumbled at the table with his hands, feeling the rough texture of the wood. It came to him then how much he had taken his sense of touch for granted, and how inaccurate it used to be. Now he could feel every grain of the wood, every knot, every splinter. He felt areas that were slightly rougher, as if the carpenter had been sloppy with his planning. It seemed like his various senses were now many times magnified. He lay down on the board. Leather straps snapped into place around him. Momentary panic filled him as he was restrained. It increased as power blossomed in one of the nearby figures. “You will learn to do these for yourself one day, but for now, you must accept them from others. Be still,” said Illidan. “This will hurt.”
When it comes to Classic, Blizzard's goal is to provide an authentic Vanilla experience, but they also needed to come up with technology to handle many players at launch, which is similar to sharding. While the use of this technology will be limited to the first month following launch, many players are questioning this decision and wouldn't like to see layering in the game at all.

Along with revealing the WoW Classic release date, Blizzard also listed plans for both a beta and stress test of the game. Players who opt-in for the testing on their account manager page and have an active subscription will be randomly selected for the beta starting May 15. Then the developer will have three stress tests where players can log in to play the game for a short period of time on the following dates:

3. Your DH wants to make sure they're in on any information about the Legion that anyone else may have, and this would include the occasional visit to cities, where information flows densely and freely, and it's easier than trying to weasel your way into military meetings with military units that might not really trust your fel-infused butt. But if Mr General is having an ale at the bar, you can probably get him to blab at least something he might know that hasn't been shared yet, especially if you've provoked him into ranting at you just with your mere presence.
“As we’ve discussed before, the nature of WoW Classic sometimes invokes different memories for different players, and this leads to certain misconceptions for some about what is or isn’t working as intended,” Blizzard wrote in its official forums. While the developer did not reveal the specific numbers, there seemed to be too many bug reports for things that were actually working as intended.

When it comes time that the body and mind have been prepared for the ultimate task, the potential demon hunter enters into a summoning circle surrounded by a binding rune. In the middle of this summoning circle, a single demon is called forward and the potential demon hunter is forced to fight for their lives without any help from the outside. The demon in question that is summoned is not influenced by the summoner, but the potential demon hunter within the circle might influence the demon that is summoned by a particular hatred or wish for vengeance upon a certain type of demon. If the potential demon hunter is successful in killing the summoned demon, they must then devour the heart of the creature as well as drink its blood. The binding of the demon’s soul to the demon hunter is extremely powerful, one in five surviving the ritual. As well, the demon’s flesh is extremely difficult to keep down, as if it tries to sear the inside of the body and crawl its way back up the throat of the potential demon hunter. After devouring the heart of the demon slain, each demon hunter is given a vision of the Burning Legion, witnessing the horrors of their enemy for themselves, ending with all potential demon hunters gouge out their own eyes. In the wake of the ritual, almost all successful demon hunters pass out either due to sickness, shock, exhaustion, or overwhelming fatigue.
