I saw people reporting they were getting RQ on and getting penalized and checked with the server team to understand how it works to make sure this wasn't the case.



Someone who rage quits is (obviously) disconnected from the server. The person who is rage quit on is returned to matchmaking. If a match ends before it concludes, the player who is no longer connected to the server is penalized, not the player who stays connected.



As an example, lets say you stay in training mode waiting for matches, get one and then someone pulls the plug on you mid-match. You'll be returned to training mode waiting for more matches and wont be penalized.



That said, I'm keeping an eye out for any videos that show someone who stays connected is penalized but I haven't seen anything. If anything comes up I'll definitely pass it along to the team.
