I don't really see why this is something worthy putting on the forums in the first place. It doesn't maatter if it's a tank/dps/healer, when a person is tired he tends to be a bit more harsh or carelss with his response. Things like this happens all the time and i honestly don't think you should single out tanks if you're gonna address this issue. Why not address the larger issues of bots and gil sellers while you're at it? printscreen that and post it on the forums, lol. If every player were to be given a reaction to every time they said something that sounded careless we'd all be here.

Also why even post the youtube clip? self promotion? - waste anyways
