There are two parts of the quest chain for each continent. The first part involves defeating numerous Master Pet Tamers, and the second requires you to triumph over the Grand Master Tamer. After you've bested the Grand Master Tamer, dailies from each Tamer will unlock for that continent. All the dailies continue to reward experience for your companions, however only the Grand Master daily quest will reward the Sack of Pet Supplies.

Felhound: The felhounds serve the Burning Legion as their devourers of magic, their forerunners, and torturers of spellcasters. An endless desire to devour magic is their greatest trait, especially when paired with their endless appetite for wickedness. Demon hunters who bind themselves to these creatures are no doubt the masters of defeating spellcasters, seeing their spell-weaving enemies as little more than fonts of power to draw from.

Question: for the demons listed, I'm particularly curious about Nathrezim or the new 'Inquisitors'. Basically because I want a very cunning, manipulative demon and strategist that my guy absorbs. However I am unsure if this is feasible, as I don't know their status and although my Demon Hunter is a proven warrior... well, he wasn't one who stood too much above the others. (Working on the backstory, but one thing I am fairly certain of though may change is he pleaded to be allowed to take the trial to become a demon hunter with the next group Prince Kael was sending to Illidan.) So although he might get lucky, I can't see him overpowering someone who is as powerful as some others.
It is completely acceptable, but harder to write, that your character has been a demon hunter sometime after the War of the Ancients. This is no different than people who have written ancient druids, and it poses the same exact problems in writing. I would not recommend this to anyone who is not a seasoned veteran when it comes to writing characters, as the longer your character has been a demon hunter, the older your character is, the more difficult to control the fel magic within, the more detached from society, and the more withdrawn they may become. Overall, it becomes incredibly harder to write.
The leveling guides on my site are essentially speed leveling guides.  My leveling guides are the same guides I use myself to speedrun to 60 on new servers to get 60 server first.  I list many occasions where I tell the player to "die on purpose" to go faster.  I tell the player to skip certain quests, because some quests are just not worth the time/XP.  I list tricks and shortcuts to go faster so you can reach level 60 much quicker.  I am still constantly going through them over and over again perfecting the guides to make them faster and easier to follow.  For the most part, the guide can be followed without the need from other player's help, as the whole guide was made from a solo run anyways.  Although I do list quests that can optionally be done if you have a group.

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)

Occasionally it's also been proposed to re-randomize all the gear. We didn't have best in slot lists back then. People weren't starting out as a fresh level 1 character with a complete list of which dungeons to run at 60 in order to gear as quickly and efficiently as possible. Now, all that data is available. If gear were re-randomized then all of those lists would become useless and thing would be close to how they were. Which is a more important part of the "vanilla experience?" the fact that item X from boss Y has exactly Z stats on it, or the voyage of discovery? Personally I think that voyage is way more important. Do you remember how many points of which stat on the ring or whatever that Darkmaster Gandling drops? I don't. Would it kill your experience if the BiS for every class were in a different dungeon so people had to actually play to figure it out rather than simply consult a spreadsheet? I don't think it would. For that matter, it probably wouldn't be a bad idea to handle it intelligently so that the better gear is in later dungeons. I remember there because some weird cases where level 40ish gear was better than anything that dropped in level 60 dungeons.
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.”
