This is really annoying, They register them self in DF for a hard mode primal fight, yet when the confirmation comes up for everyone to click to go in, they click it, and as soon as they get into instance they quit? why press the confirm button at all? it just makes it longer for the rest of us when they do that as apposed to just withdrawing before going in.
I don't think it has anything to do with them not liking the people in the instance because they don't even give enough time to check everyones gear.
