Hey guys.
Today, I was in Deadmines heroic when, just for fun, I used distract on the Defias Evokers (Defias Envoker - NPC - World of Warcraft).
To my surprise, it dispelled the Envoker's Shield (Envoker's Shield - Spell - World of Warcraft).
I doubt that Blizzard intended this ability to remove the Envoker's buff. I hope this helps you go through Deadmines a little faster if you have a rogue in the group.
