Sigh WoW. But its true, I dare someone who plays to say this doesn't happen. ALL. THE TIME.
Dark Touched Warriors. Naxxramas.
Does not every melee idiot go running into them gleely swinging their 2h weapon like a tard expecting to survive? As a retribution paladin, and usually the person in charge of my raids melee mashers, I have a macro to remind, to VERBALLY TELL THEM, to stay the feck out of that mob until they go down. Will someone still die? Yup. (*cough* is it usually a rogue, I think I think it is.)
I cannot hate those NPC's more.
