This guy went off and calling me retard and I countered basically all of his insults (probably shouldnt have). So we get to the Sha outside part of SPM. He immediately jumps into the middle of a group with tank not even close to pulling. So i let him die. He comes back in as we are downing the group he pulled, grabs the rest of the entire area. we wipe but before he dies he sends me a brez (didnt look to see who it was from also didnt realize he was still in combat) Took it died again. He loved this of course it is at this point I told him I'm over it and want my free valor before raid time.
Him and tank leave. I apologized to the DPS that remained and asked if I was being unreasonable because it made me feel toxic because of all the drama, they said I wasn't being crazy. We finished the run very quickly thereafter.
Now this made me realize that healers should have a Sacrifice Stupid button which let's you Sacrifice the player who either holds aggro majority of the time or who pulls first. Now what this would do is give everyone a shield that was modeled after that persons corpse or something. This is my solution :)
