Alright, so i don't think this will be a repost.
So, in Zul'drak, you're gonna find a little village south of Light's breach, were there is a few mobs, etc etc.
But what you want is to go outside of the camp, where you will find some friendly NPC's attacking invading enemies. Now, all you have to do is to hit them once, and you will gain the loot.
Notice, that i am not in combat on this picture ^.
I hit him but once, and i got to loot him.
Maybe it works at other situations like these, with friendly npcs attacking hostile mobs, but as i remember you have to do around 50% of the dmg everywhere else. But sure, if it isn't like that, go ahead and flame me.
Shouldn't be used if you're trying to level, as the Xp you get is minimal.
Hope it helps, if not, then err.. something.
