Okay, so I was healing a dungeon with a buddy of mine who was the tank. For some reason I decided to spam levitate on him, and I found that if he didn't constantly manually click levitate off, he would generate no aggro. I tried it again in another group, on a different tank, and wound up getting him kicked because he could never hold any of the mobs off of the dps.
Could be useful if you wanted to get a tanked kick, or you just feel like being an *******![]()
