I always like being different. And I always have thought that humans are boring. For alliance I love dwarves (ever since good ol' D&D days). For Horde, the Taurens are kick ass (and were the only shamans for ages), and who doesn't love a zombie?
BTW Kallieen: Love the sig! D&D, AD&D(1,2,3 Editions), Rolemaster, Spacemaster, Warhammer fantasy, Palladium Fantasy, Rifts, Paranoia, Amber, World of Darkness... the list goes on
