Muting someone in-game should also mute them in the post-game lobby.
I feel like if you mute someone in-game, chances are, you don't want to hear from them in post-game lobby. This problem has been a major issue for a long time. You basically mute someone in-game because you don't want to hear from them and they nothing productive to say. Would they have something productive to say in the post-game lobby? Probably not. So please riot, it would be nice to make it so the muted person stays muted entirely, not just in-game, but in the post-game lobby.
