People can be toxic if they are doing good in game?
I've had this guy 2 games in a row where he went yasuo first game and riven next. Both games he won lane and got alot of kills but when he went yasuo he fed a lot too and blamed it all on me specifically, the support. I was talking back to him whenever he would flame when he died like "WTF ARE YOU GUYS DOING THERE ARE 3 TOP" and I would say you are overextending just group. After that it was "report the support plz" and "i dont get how somone can be so fucking bad". The fact that he had a lot of kills in game however made it so that no one but me would report him. I mean then again, he is a riven yasuo main.
