If they're low, I just scare the crap out of them. On my priest I loved playing with Mind Control. MC them, then fort them, and their health goes down and they freak out... then put a low rank of SW:P on them so they start to die... then MC them again and renew or prayer of mending them... just keep effing with them like that...

Me and 2 other priests once MCed a 60 gnome rogue (at 60) into Thrall's room... we'd take turns MCing him while the other two healed/regened mana. He had to corpse run like 3 times to get out. (he wasn't about to spirit rez, he was in T2 with TF lol)

I wish every group of 5 I made could have a priest... just for MC shenanigans lol.
