When you mind control one of the Kor'kron Grunts outside of orgrimmar (as a priest; unsure if other control methods work) when you use their melee ability they will shout something in chat. This will happen EVERY time you use the ability causing everyone's chat in the area to be spammed. The main use of this is simply annoying people dueling outside of orgrimmar. I was debating between putting this in guides or exploits but since I doubt the spam created by these mobs is intended I believe this to be more of an exploit.
