The angel class would be cool. And there former human so that can relate. i would love that:thumbsup:
Correct me if I'm wrong, but aren't humans the result of Nephalem (offspring of demons and angels) interbreeding? I figure the power gap between, for example, the Witch Doctor compared to an Angel is sort of steep. I'm not saying Blizzard can't force it into the game, but I don't see how it would work, lore-wise.
Sorry to be a killjoy.
Back on topic, considering Diablo is sure to make an appearance in Diablo 3, I wouldn't be surprised if there is indeed a hell area.
However, I also don't think it would be too much of a stretch to think the story (and the slaying of Diablo himself) could conclude in the final expansion. If that's the case, I'd assume that they would hold off on a true Hell area until then. That will essentially keep fans on a cliffhanger (and probably piss them off).
Anyways, I'm not sure how they'll implement it, but I'm sure the last act of Diablo III will be an especially diabolical one. If it doesn't take place in the actual fiery physical hell, I'm sure it will take place somewhere that will feel and be just as evil.
