What would you want in a World of Warcraft 2?

Your guess is as good as mine as to how serious Blizzard was being the other week when it floated the possibility of a sequel to World of Warcraft during an interview. After all, words are cheap, but development is crazy expensive.

But let's have a little fun with this concept today, whether or not a WoW 2 is in the making. Assuming that there was one being brewed up, what would you want to see done with it? Would it embrace more sandbox features? Would it simply remake the current game or jet off on its own timeline? Would you even prefer a platform switch, such as a mobile WoW or a virtual reality-based one?
