What about a "reverse prisoners island" for ranked?
So, Riot has stated some time ago that they will not put toxic players in a "toxic-player-queue". They have their reasons for that and they might have a point, but what about doing something different? The prisoner#s island idea has the following thinking: toxic players will be marked and are matched more often against other marked players. But what if you don't mark the toxics but the good and nice players?
Result: those who play nice, are helpful and sportsmanslike get rewarded by being put with friendlier teammates. That's better and more rewarding than some "honor" no one cares about and that gives you maybe, MAYBE a tiny ribbon for your loading screen.
Why is this not a thing yet?
