A idea that might REDUCE toxic play
Why not totally remove the chat in the game, and instead implement commands or more pings to communicate. I feel that the chat is not used to coordinate anything anyways. I have had games where everyone is doing good, so no need for framers to flame and we only used pings. I believe this a better approach regardless of what is lost if the chat is remove because it would take away the only way to be toxic towards someone.
