i completely disagree. I think WoW is successful because of its interface to the general consumer....all of the user mods enhanced it but if blizz listened to the community and is implementing what works why would that be bad?
i love it, now they just need to start expanding into the idea of making the interface work on consoles and ill orgasm.
from what I recall, in diablo you use the mouse to move and do actions.... in WOW, you use the mouse to look... the two games are different and thus the interface should not be the same.
this is not a MMO, it's dumb to have skill trees where you won't use 3/4 of the skills because you have limited points.... what if every character rocks? it's not about PVP balance so there is no problem with you kicking ass... monsters can be boosted health wise.
