Still, people in this thread have time and again stated and I feel it should be re-iterated : We don't expect perfection, but we do expect effort and some modicum of improvement. If you did both of these things and the person still left, then I'm very sorry you encountered a jerk when you were trying to do everything right. No one should verbally abuse you either, I'm sorry to hear that and I sincerely hope you reported them.
Or could have been as easily someone who didn't have a clue, didn't read the description and joined expecting a one-shot carry also.
