i'm also not too keen on the barbarians rage system... sorry, fury system i mean. barbarians are certainly not being based on wow's warriors - that much is obvious from them changing the names of the talent trees (sorry again, i mean skill trees of course.).
its not that i mind particularly, i love playing my warrior in wow... but i've already got that, why would i want to play the same character in a different game? (actually, put like that, it sounds pretty awesome. maybe they should do that
)
