Orc, good racials. Increased SP and reduced stun duration.

Cow is too big, gets kinda annoying IMO. Maybe female? Increased health and war stomp. Probably better for PVP?

Trolls look good and there are not enough of them. Racials good too. Increased regen, increase haste.

The most important aspect is how they dance. Do you want to rock out like MC Hammer? Do the Jungle Boogie? Or dance like Uncle Jojo after he had too many at the Bar Mitzvah?
