Pretend that it's been confirmed that the next expansion is about the Burning Legion, how would you do it?
Not just - no, it won't happen.
Where should it happen? What should be the lead up/pre-expac patch? What features would it have? Which characters should appear, which and how should some change? Like Maiev, Illidan, Alleria, Turalyon, and etc. Would you want to see an updated Stromgarde, blood elf/draenei zones, or Gilneas? Should there be little Horde presence and a stronger Alliance appearance? Who would be the villains? Should we see sub races like broken or other related races playable along with some classes related to those races? How would you do a Demon Hunter class?
Blizz is bound to be working on the next expac right now, what would you like to see them working on?
