I'm sorry but you don't have to read the after game chat. In game chat you kind of have to due to the need to communicate with your team, i personally turn all chat off now because there's no use for it. After game chat is not in game, they did not ruin your in game experience, that is what the tribunal is about. Simply leave after the game. Say "gj team" or whatever you need to say, then leave. If you stop to talk **** to people then you are no better, there are 2 real uses for after game chat, to argue and to say GJ. No need to stay for a long time. Sorry.
and yes stop comparing real life situations to the game it's ridiculous please learn to separate the severity of situations.
