Haha, never had an issue with regen aggro. Can be dangerous in Ala Mihgo and other dungeons where mobs aggro just by stepping into their aggro range. I usually ask if the healer wants to heal large pulls or chill out and netflix it up but this is a great way to get back at tanks that just rush in and assume the healer is ok with it. Haha I might level up my WHM just to troll, get kicked and requeue like nothing happened, huehue.
