This thread is pointless, since you assume Classic + will be a thing, when it will not be a thing because we have no source that say it will be, and more source that say they work on Burning Crusade.
The future is Burning Crusade and Wrath Of The Lich King, and developers already worked on racial nerf on theses expansions. Why they would reinvent the wheel ? Why they would reinvent something they have done ? There’s no need to “evolve” Vanilla since it’s a game that is not here to belongs forever, and the success of Vanilla is part of the pure lack of balance between each race and class. Change the meta game or whatever and you end with a new game, and I doubt it’s the project of Blizzard.
