There should be a way to chat restrict myself.
This is one of those suggestion/player behavior improvement things. Sometimes I'm feeling really bad while playing league, either I'm tilted or mad about something irl or whatever and I want to vent at my teammates by sarcastically mocking their play or just being a bad teammate in chat. Because I realize this is a tendency of mine if a teammate responds to the things I say I often apologize for being an asshole and tell them to please mute me before I tilt them but I have never once seen someone actually do it. There should be an option for me chat restrict myself so I can type in the chat bar but no one can see what I'm saying, similar to how a chat restriction works.
