Make (...) and silence a reportable offense. Seriously.
Sometimes when playing in a game if I make a bad play or a mistake and die I'll get a ... In the chat which is really unsupportive of your teammates because they are supposed to work with you to Achieve victory. Worse still is when they are silent after a bad play, not even reassuring that it'll be ok and can be made up for. If teammates are supposed to be on your side then make this a reportable offense. To be silent after a bad play implies a toxic, judging attitude. It is absolutely unacceptable behavior, teammates need to either be reassuring THROUGHOUT the game or not play at all.
