Add an option to disable post-game chat
Disabling post-game chat would make playing as Killer less stressful because Survivors tend to either complain or brag after a match and can easily gang up on a Killer, making for a toxic environment. Survivors always reach the end-game screen before the Killer does, so the Killer is forced to see Survivor messages before they can quit a lobby.
This might also be nice for Survivors too if their teammates sandbagged or didn't do well together in a game. Just the option to disable chat for both sides might make the game more enjoyable.
