Just today I was doing a level 28 Poe and we had a guy who would just hide in the corner of he map and crouch invisible through the whole thing. We kept shooting him and trying to get him to participate but he wouldn't. Then when we were done he fell down to the treasure room and died! Hahaha. We tea bagged him vigorously and took our rewards for ourselves. Talk about a time when karma has had your back or about when it bit you in the ass.
