While Orcs are indeed quite awesome, I think you should go for Undead or Tauren because their racial abilities are much more usefull for combat, especially PvP.

If you're not gonna go for PvP, then any of them will be fine, but you'll find that WotF is perfect against a lot of casters and mobs. Warstomp also kicks serious ass against everything.
