A side note: PvP (besides the gear inflation) in Warhammer isn't that bad right now.
Yes, the engine still sucks, but there isn't any of this ping-pong ball syndrom ******** (since knockbacks trigger a knockback immunity), you can't be stunned for longer than 3 seconds without having 30 seconds of immunity right afterwards, and you can't be rooted indefinitely since you also have a root immunity timer.
Why a mmo doesn't realize that NOT LETTING YOU CONTROL YOUR AVATAR is a bad thing absolutely astounds me.
Also, market research shows that the vast majority of WoW's monetary success comes from "carebears," or the more casual crowd. Hardcore raiders are NOT what drives a model like WoW....more something like EvE.
