Kaivax, a WoW forum community manager, revealed that WoW Classic's class design, battleground mechanics and stats on existing items will be set to their 1.12 state, despite the game releasing content that expands beyond that. This removes "progressive itemization," so if the stats on a specific piece of equipment was changed during the original updates, that won't take effect in this version.
Nov 15 I pay $12 for FFXIV. Why pay $15 for Classic? I copied this from a reply I made with slight edits, but I feel this should be brought up in a post. I'm mostly a FFXIV player nowadays. I used to play classic a lot and have only played modern WoW on and off because friends kept bugging me to come back... and then we would all quit a month or so in. I currently pay $12 for FFXIV because they have an option to pay 12 for having only 1 character per server. Paying $15 dollars for an old game that was already released is just too much. I don't like modern WoW at all. I don't like the changes they are making to 'their classic'. If I have to pay $15 dollars for a game I won't play and a modern Blizzard's take on classic WoW, then I'm not going to pay anything and go on private servers. I don't like private servers either because the people running it are often corrupt and you never know when the servers will be shut down, but I am also not willing to shell out $15 for something that isn't worth it. If I can pay $12 to play FFXIV which is a modern mmo that receives constant updates, I shouldn't have to pay $15 to play an old MMO that's already been released and is getting unnecessary changes.Destroynme111 Nov 15
Things like Tauren melee reach being bigger, which is something I experienced going away live during Black Temple Illidan progression (at least for that particular encounter), is confusing to players as it's a significant advantage over other races in some instances. No quest tracking is another apparently confusing issue, as many Mankirk's WIfe seekers well know, and there's a whole lot more where that came from:
Nov 15 We ordered vanilla not vanilla with sprinkles 1. Sharding/Phasing was not a part of the classic experience. The launch surge and often times overwhleming population fighting over quest mobs and loot was impactful on a human level which brought people together to make parties so they weren't fighting or made people bitter rivals. And that ten minutes you spent competing with people to loot that bucket before it despawned for another few minutes was intense. 2. Loot trading was not a part of the classic experience. Ninja looting was a real thing, a crime you could commit which united the community up in arms against you, blacklisting you. That's a feature for modern WoW, not genuine classic. This is a recreation. Not a remaster. Not reforged. We ordered vanilla, not vanilla with sprinkles on it with modern hand holding baby coddling streamlined bogus. That's more suited to your modern WoW playerbase, not the millions waiting patiently for the game they knew and loved over a decade ago. I don't want to sound like an entitled brat, but when you advertise a product, don't change it behind the scenes. Please Blizzard, don't add these things. They kill aspects of what made classic wow such a special phenomenon that rallied people to make private servers in its honor. I'll go play one if this isn't authentic, because those unofficial servers would be more authentic.Rhystael95 Nov 15
Escort quests can take awhile to do.  I have thoroughly tested all the escort quests in the game for time/xp.  Most are worth doing, but as long as you are able to actually do them without failing.  Most require you to pay special attention to the escortee as most are fragile and will die easily, so do your best to keep mobs off of the escortee during escort quests.  The longest one in the game is the Tanaris chicken escort.  The chicken escorts are only worth doing if you were able to do all 3 of them, as if you do, you will be able to turn in an additional easy quick XP turn in quest at BB, which makes them worth it.
So we asked ourselves, would it still be possible to deliver an authentic classic experience if we took our modern code, with all its back-end improvements and changes, and used it to process the Patch 1.12 game data? While that might seem counterintuitive, this would inherently include classic systems like skill ranks, old quests and terrain, talents, and so on, while later features like Transmog and Achievements would effectively not exist because they were entirely absent from the data. After weeks of R&D, experimentation, and prototyping, we were confident we could deliver the classic WoW content and gameplay without sacrificing the literally millions of hours put in to back-end development over the past 13 years.
My main plan will be to focus on raw gold in the beginning. Then I will spend my gold on leveling tailoring and enchanting so I can shuffle enchanting materials which is likely to be very profitable. I already have some shuffle ideas, and I will look for more. Then I’ll work on obtaining the rare enchanting and tailoring recipes to craft those for gold.
