*Suggestion*: When you mute people in-game, they should stay muted in post-game lobby.
I personally think it would clear up a lot of pointless tension. I can't imagine a scenario where one would need to speak to someone they felt the need to mute in-game as opposed to post-game. Correct me if I'm wrong but I tried to attack this from different angles and couldn't find a possible case situation where this wouldn't be a good idea lol
