I (healer) got votekicked because a tank and their friend didn't like that somebody else pulled mobs before they did (it was the other dps...)
I tried my best to ask if they were still able to continue or if they had an emergency, and they just didn't reply and stood still, occasionally targetting me or the other player...

Then they just went afk and refused to do anything for the next pull along with their friend, so there I am doing a trash pull with just me as a healer and a dps...
It worked but I don't really enjoy people AFKing if they queue up for content, just to votekick the people actually playing the game for them...

I've healed dungeons without tanks with friends for fun, it's a good exercise so it wasn't anything I lacked confidence in and I was OK continuing for a few pulls or even the entire dungeon if it was a real emergency for the other players, but man...
AFK griefing and then votekicking the people carrying you while trying to accommodate you...
