What some are missing is what most enjoyed about MOP demo wasn't necessarily turning into a winged demon (though it was cool, and could have been easily kept and renamed for the sake of DH's), but the playstyle. The current demo, while cool with the demons and such, is an objectively clunky spec by any MMO's standard. It feels unpolished, almost beta build-esque. They don't necessarily need to completely overhaul it, but they need to adjust the way it plays.
