I'm against racial bonuses, but racial abilities that are useful but pointless for anything serious. While WoW hate seems high here, a good example does come from WoW in the form of Cannibalize, which let you eat Human/Zombie corpses for 10 seconds to restore HP every 3 minutes(iirc on the CD). In the long run it did save you some cash on food(which was dirt cheap or free if you were/knew a mage) but it didn't provide any gamebreaking benefits in endgame or PvP. (For the sake of arguement, lets not touch things like Stoneform or Will of the Forsaken)
While being ultimately pointless, abilities of this vein would add variety and make the races more unique.
