For those who have encountered members of a group or players that really piss you off, what are ways you have struck back at them?
For me, I remember a Heroic: Halls of Lightning run in very early Wrath of the Lich King. There were a number of DpS that were pulling the mobs because they thought I would pick them up from them and they "Were just having fun." A number of other pulls into the instance when they kept doing it, I snapped and tried to pull the entire instance in one single pull to make the DpS suffer and to make the healer who was condoning it suffer with their 100 gold repair bills. It was really fun when we got to the room with the vrykrul statues.
