Its still a dumb reason to not like a game.
I take it then that you never played Diablo II?
Aside from being the best RPG ever in terms of game balance etc, it was also the best ever in terms of atmosphere. Everything, the plot, art, environments, etc pulled you into a dark and violent universe that was badass beyond anything WoW ever had going. It wasn't immersive per se, but you felt like a beast when you slaughtered a horde of Moon Lords or Death Clans and then looted their bodies as they lay in a mound of blood.
Basically, there's no excuse, this is a step backwards in terms of environment and aesthetic, if they didn't have the technology to do it right then I'd prefer that they didn't do it.
And if you think it's the only reason you've got the IQ of a garden hose, It's very possible that it's a sign of things to come.
Damn straight.
I really don't like the look of the barbarian, too bulky. He should look like a wrestler, not a sumo wrestler.
And wtf with no Necro? I realize that the witch doctor and necro have some overlap, of course, but in that case I'd prefer they axe the witch doctor. Necros pwn. Get rid of paladins, amazons, etc. And one new class is fucking lame. It reeks of "save it for the expansion." Not to say I'm not looking forward to this game, but when you release a perfect game I expect that the follow up is also perfect or near perfect rather than just an extremely good game, which is what it seems to be shaping up to be.
