Muting a player should follow into post game lobby
Basically title. Riot's only response to dealing with toxic players is to mute them. As such, the mute should follow into post game so that they can't continue the harassment in post game where they can't be muted. While I'm at it, here's an idea, muting a player should follow through to future games. Many a time have I had a player I needed to mute, reported and queue'd right after game, and was in game with them again.
