Yesterday I was run through some quests by a shadow priest. Because her attack had no animation, it looked like she was killing the mobs just by coming near them. Do any abilities actually do this, and has anyone managed to kill a mob without attacking (or letting it attack, as would have to happen with Thorns and Aura of Retribution)? What's the highest DPS anyone's achieved this way? Rogues think they're hot stuff with their one-shot kills; let's one-up them!
