What ever happened to "everyone is allowed a bad game"?
I have a policy of not saying a fucking word in chat because I know that everything I say, no matter how innocent, will always be taken as "toxic". So I play every game basically with all players on mute. Then ONE fucking game I get a complete fucking ass hole on my team who actually does everything in his power to help the enemy team win, so I tell him to go fuck himself, and BAM, immediate chat restriction. No fucking second chance. No warning. No "everyone is allowed a bad game" once in a while. Nope. Just instant punishment.
Go fuck yourselves Riot. You are your witch hunt system needs to be burned.
