So I've been leveling my Worgen warrior lately. Picked up taunt. Thought it wasn't anything special, sidelined it because I decided to spec Arms at first. At 18 I respecced into Prot for instant random queues and of course hit taunt and AHMAHGAD WHAT I JUST ROARED AND I HEARD IT AND STUFFS
Also you roar when you change stance.
Worgen warriors are the best class/race combo for this reason alone.
