It'd be nice if when you got a chat ban like I did, Riot let you know that yes, they did indeed also punish the feeding, trolling buttmonkey that caused you to tilt and swear up a blue streak in chat. I'm fine in chat most of the time, until some AFKing dink ruins my promos, or some moron Pantheon gets stomped top, wanders mid without asking if he can switch, then proceeds to feed there too and ends the game with no kills, few assists and yet I'm the asshole for telling him to not suck.
I'm fine with being the asshole but the chat bans aren't addressing the real problem. Bronze 5 is a seething cesspool of feeders, trolls and AFK griefers who continually destroy games of people who are just honestly trying to rank. The problem isn't some bad words being dished out to people who deserve it, the problem is the people who deserve can and do continually ruin 40-60 minutes of people's game time night and night, month after month, year after year and it never seems to end.
