I <3 the Selonians. I love their voice, it sounds so evil but then they look like ferrets. I get tired of being a human, or race that looks like a human constantly. Being a creature/animal would be a nice change in altland. I do realize that it's much more work for them and we probably won't see it, but that's what I would love to see. Jawas, wookies, cathar, and whatever Broonmark was, would all be great. Also I really enjoyed every aspect of Voss and would be happy to play a Voss if their paint job was customizable.
So for me, any race that is an animal/creature is what I really wish for....
