I'm not sure if this applies to any class other than Black Orc, but Taunt works in PvP. Not in the traditional sense of "forces the monster/target to attack you" but it DOES increase damage taken by said target by 30%. Its an amazing ability to open up with on whatever you're bashing. It not only makes you do an acceptable level of damage with a 1 hander, but it makes it considerably harder to heal them. The effect lasts for 15 seconds or until they hit you 3 times. Pretty awesome imo.
