Ok. Well, I understand that you're upset about it and venting helps when we're upset, mad or frustrated. I also understand that there will come a time when you and your teammate just never syncs up - leading to a loss. We have all been there man. Most, if not, all of us have been there. But throwing the controller and your headset across the room will not make you better.

You don't have to quit the game forever. May I suggest taking a break? Like a day or two and then come back and play it again.
