When I've done the raid on all my characters for the week I mostlikely just post an LFG with a text like "Willing to help out any group no matter what part". If the group I join has someone who leads the group and is really toxic I start to troll around aswell. But not by wiping on purpose. I troll him with my sarcasm, calling out each of his little mistakes, backup the nice people in his group and when He is AFK I just push him into his death which is always really funny when he comes back and ask "WHO THE HELL PUSHED ME OVER? -blam!-ING JACKASSES". Most of the time the group doesn't tell him who it was and backs me up since I backed them up aswell. The jackass leader then leaves most of the time and we can do a nice and easy run.

I mock them by getting mad at them whenever they do something (even if they're doing it right)
