you should be allowed to leave.
You should be allowed to afk after a certain number of surrender votes. Its extremely toxic to be in 4v5 matches where your team refuses to surrender and you play a extremely unfun match for 45+ minutes only to lose anyways. So make 2 surrender votes then let people afk out matches please. Its like being held hostage when your stuck on a team that refuses to let you go. Its insanely stressful when this happens and its one of the few things that makes me rage in this game. Either let people leave or shorten the average game length to 25 minutes or something.
