The current system for surrendering is freaking awful. The second a surrender vote fails and the match has hit a point where it's beyond redemption (1 in a 100 match miracles notwithstanding), everyone involved starts playing the blame game and getting real toxic to each other. The worst part is when there are two holdouts that are specifically doing it, believing they are somehow punishing the rest of the team, which in turn just leads to more arguments and toxic behaviour. This then spills over after the match too.
I am not entire sure how to fix this, but there must be a way to change the surrender system to make it easier to surrender when a game has turned into a complete mess. I believe doing so would remove the vast majority of the toxicity and toxic behaviour in this game.
