Tauren - Warcraft equivalent of Native-Americans. Strong, Wise, Spiritual, and Protectors of the Land. PLUS, they are minotaurs, and minotaurs, as someone said earlier, are sexy [the males, not the females!].
Draenei - A race that looks evil, but is trying to be good. Kinda of a redemption theme going on, but with magic. PLUS, they too have a sort of minotaur theme going on [and their females ARE sexy, males not so much].
Worgen - Need I explain?!
Scyther - LoL
Satyr - Warcraft version, but mixed with classic. IE Like to party, and like to kill.
