Because they're jealous of our awesome sexiness, that's why. No, really, I don't know. I think dwarves are pretty cool, and the dwarf society was very interesting. The Orzammar questline had some of the hardest decisions in the game (which is a good thing), and playing as a dwarf you get a whole new perspective on it. I didn't care much for Oghren, but Sigrun was hands-down my favourite companion in Awakening. Though I have to agree with RustyBlade that the beards in this game look terrible. Fortunately DA dwarves aren't as beard-obsessed as those in some other stories XD.
