People should be able to leave the game
I think one major disadvantage in the game and the core of the toxic community is that you are punished when you leave the game.
The probem is if you encounter trolls and bullies, you cannot leave the game. You have to endure the trolling and the bullying.
That builds up frustration until the bullied people are starting to bully themself. I think the possibility would gradly benefit the game.
To avoid "allways leaving" you can just build in a kinda of "leaver hell". If you leave often, you are qued with people who also leave more often.
Espeacally for killers, there is no real reason why they shoulndt be able to give up. The Survivor will get their Points and save their items and everyone can make a new game
