I have always wanted to see the humans become more than just the "default" race that everything is based upon. Oh, sure, 1ed gave them unlimited levels... which was given to all other races anyhow. And 1ed allowed the humans to be any class they wanted... which the other races were allowed anyhow. Then only humans could be Paladins... which the other races (especially elves) were allowed anyhow. And the downside? Humans got no bonuses, and were not allowed to multi-class (which they are now).
Yeah, I think the humans should catch a break this time around.
