The video also explains that "rage doesn't win games," noting that the win rate for zero-rage teams is 54%, while teams with three keyboard-smashing players sink to 46%. The numbers get worse from there. Players who avoid flaming in chat and instead work to refocus their team see higher win rates overall. Riot also tracked the way individual players rank based on behavior. Players with a positive record of behavior win 10% more games than average players, while players with a history of community reports win 35% fewer. The decline generally starts with one loss, which starts the raging, which in turn causes more losses.
