Since WoW Classic server has been announced at Blizzcon 2017, there is not much info about the server revealed. It is known that the upcoming expansion Battle for Azeroth pre-order has been available at blizzard shop, and the system requirements of Mac and Windows has been unveiled Recently, Forbes has an interview with J. Allen Brack and Jeremy Feasel about the project and some of the vision that developers have.
They seem to have expected some things, though, see adding pets with aquatic damage (gun and ooze) aswell as a resistant cockroach to stop us from cheesing everything with elementals. Yet, a fact their damage output is low combined with shields not checking for racial damage means this mechanic prevents a lot as you mentioned. The last boss has got an ability to remove basic shields so perhaps that was not in oblivion either… unlike the reactive damage. Also, an ability that forces swap altogether with an ability which prevents from being swapped, including critters? I can't say I like it.
You can profit with cooking, as Savory Deviate Delight was much in demand in vanilla warcraft. I got mine from mobs in the Barrens, but I believe the pattern also drops from mobs in Mulgore. Either way, the raw fish comes from the pond/lake at the Oasis outside Wailing Caverns. The cooked fish doesn’t just turn you into a pirate or ninja, but you can also gain faster casting time, or +rage for tanks mid-fight, +energy for rogues. (Not for feral druids. There is no such thing as feral druids in classic, they’re all healers with the occasional moonkin!!)
I started playing with WoW Classic like a couple months. I would not call my self old school or a vanilla participant but damn much when I began playing WoW Classic has been alot more entertaining than it is now. I didn’t really care about this particular WoW Classic release until yesterday. I am actually hyped to play with this. We see more staff work in the world and participant connections. Folks rarely up set to do anything at the world that is open and seldom speak to each other. Ive gone multiple days where il try to begin convos with players and its literally like trying to start a conversation using a NPC.
The quickest way to level up is to travel through the game's zones, completing all the quests you encounter along the way. Completing quests grants you Experience points, which will slowly fill in your experience bar with blue or purple. When the bar fills, you reach the next level. Alternatively, you could choose to run Dungeons or Battlegrounds, which are not covered in this beginner's guide.
Logging in for the first time, being welcomed by THAT login screen and THAT music... You can't not be taken back if you've played Vanilla, and especially if you've played 2 years of it non-stop all day every day. I probably stayed 10 minutes in character creation just because of the music alone (and trying to get my character looking exactly as it did back then - although I wasn't a shaman then). The whole intro experience was especially amazing for me since the Tauren starting zone was my first encounter with WoW in the EU beta, and a little bit of that spark did return. But is that all Classic has to offer? A trip back in time when we were wowed by the game for the very first time?
2. Achieving. There are many pet battling achievements in game, and following the natural trail through the Taming [Continent] achievements up to Pandaria, and then on to the Spirit Tamers, Beasts of Fable and the Celestial Tournament was an epic journey for me and for many others. It's well worth doing. The Celestial Tournament is still, IMO, the pinnacle of PvE pet battling. However, WoD and Legion and BfA have added more battling achievements.
In the end, while it may be a huge cop-out, it really does come down to personal preference. Some people will simply not be able to handle the huge downtime between pulls, not being able to buy a new skill rank because you spent all your money on food and drinks (mages were popular for a reason back then), the very slow pace of leveling, and a whole lot more frustrations and not user-friendly features. On the other hand, the experience really is significantly different enough from modern WoW that it does feel enough like a "new" game, or at least a new and different expansion. An expansion that has many more differences than the last 3 or so, something that's both new and old and familiar. And, yes, it also offers massive quantities of nostalgia for those of us that played Vanilla, but what's so wrong about that?
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.
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.
