Elves are busted.
They have one of the problem skills in Flesh Sacrifice, and they get to pick up free abilities from eating things.
While I hope that Flesh Sacrifice gets addressed in some way, what worries me the most are those skills. It worries me because it's totally broken, but it could be a really great and fun thing if they didn't just... get them. If they got them and couldn't use them unless they had the corresponding skill, it'd be far less overpowered and introduce a gameplay element that complements the theme of having a bunch of other people's memories in your head: you've got a lot of knowledge that you just can't use.
