Change to the ban system.

[Mixt]

I have an FC mate who found himself in a comparable situation.

The context being that he was running o12 normal mode for the week as a healer, and everyone was screwing it up, dying left right and center, and blaming him alone for it, while the other healing was not even trying to heal and in fact spent most of his time face down in the dirt.

He did mechanics correctly, dodged all AOE's, healed as much as he possibly could, and all he got for it was scapegoating and harassment.

The other people in there, and ESPECIALLY the other healer could not accept that they were doing it wrong, and instead decided it must all be the fault of the only person in the instance who isn't dying over and over, getting hit with everything, or randomly AFKing in the middle of the fight.

After multiple wipes and one insult too many he finally snapped and lashed out, calling them out for using him as a scapegoat and on their incompetence and laziness, and basically called them a bunch drooling retards, after they had spent the last half hour repeatedly calling him far worse.

They promptly reported him for hurting their precious feelings, after all, it's only okay when THEY do it!

Cue the banhammer smackdown.

He is now walking on eggshells for fear of losing his account because of further incidents like the above.
