So my duo queue partner

Was duoing in the preseason, found a game where i went bot supp and we synergized so well that it was game over at 10 minutes. so we decided to duo. one week later we are duoing and he is doing shit. so after the fourth game of this i tell him that he should switch to a non carry role until he gets off tilt. his response. muted and removed after this game. and this is the story of why ranked is toxic.
