More effort on rooting out trolls, less effort on bad language?
I suppose Riot likes to focus on name calling and rudeness in chat because it's easier to find, but I've never lost a game because someone said something mean to me. I have lost a game because I had a Cait mid who said in pregame "oops, this is ranked, tee hee." I suppose she wanted to dominate anyway and tell us we never should have doubted her, but instead she gave up 5 kills and went afk. Is the person who says "ez" in allchat really a worse influence on the game than she is?
