Toxicity, Inting, AFKing - Too Much For Me

I've been playing League for several years, and the toxicity amongst players has gotten more and more extreme this season. In 3 of my 4 games today, I had teammates flame each other, int, and afk out at around level 5. It's gotten to the point where the game isn't fun anymore. There is little I can do aside from improve my play (which was actually good during these games). I don't type in chat in most of my games, and even if I mute all, it won't stop my teammates' bickering. I know Riot tries to take action against players who do this. Unfortunately, their efforts have not been enough, or punishments have not been punitive enough. I'm uninstalling League today. I post this so that maybe Riot can hear another voice of a lost customer and take steps to win me back in the future. Cheers.
