I posted this lil story on another thread, but i think it fits here as well.
After killing Varian in SW, I was on my prot orc warr, we were all running out, the Alliance had gathered a VERY large raid group chaseing us to the tram, in an act of Martyrdom, I stopped as we were fleeing, turned around, battle charged/intimidating shout/pierceing shout/shockwave combo'd them and bought our raid the roughly 7-10 seconds they needed. The Alliance, fans of mass group attaks as they are, couldn't resist the chance to gank the shit out of a Horde, so atleast 70% of their raid stopped for me. Truly was a good moment.
