Still a bit off topic, but it's cool if he doesn't like centaurs. I'm typically not a -huge- fan either, they just get overused a lot and they're often just generic baddies. But I do really like what ANet has done with them as far as models go, and some of the animations that I've seen in GW2 videos look really really nice.
That said, I still do agree that a playable centaur race would be sweet. Have always wanted to play the "bad guys" from these games--the centaurs, the naga/serpent people, dragon-things, you name it. But I think since they're usually so different that devs would have to really commit to it to overcome seemingly simple things like "where put boot armorz"
