I dont expect it to "blow warcraft out of the water", but I do expect it to bring MUCH better PVP and have learned from WoW and other MMO's about what people want and don't want. If it sucks so badly that no one wants to play it then everyone will have their WOW toons to return to, so no harm in giving it a shot while you can do nothing right now but gear up with soon to be useless gear or level up alts. That's my philosophy anyway (though I don't know if I'll return to WoW at all at this point).
