And that's all good and fine! Opinions are totally welcome, and a point to you duke.
We don't really know how much power khaine has, so the avatar may just be the proper representation we get in game. And that's all good and fine. C'tan can stay or go as far as I care, but we should get a tomb stalker or a walker or something in return. I just don't think that the C'tan are so overpowered that they should be apocalypse only.
