I don't think there's anything they can do to save WoW, maybe WoW 2.0. Have the world end in current WoW and new story take place 10k years later.
Well story is kind of irrelevant and the least important part of an MMORPG, but at least you can write the slate clean.
The whole game is a mess of systems and design philosophies that can't be fixed so they don't even try
