Not Quite Prisoner Island
As I stated, this is not quite Prisoner Island , at least in regards to being forced. It would be purely voluntary for anyone to use, could even have a warning on it when queing.
Basically; create a new que (probably on SR), Toxic Pick. Reporting would basically be disabled for this que, except cheating/bot. This would be an area where a Tilted Summoner could go to blow off steam (even though a break might be better). It wouldn't be force on anyone to play though.
My logic for it is, and I admit has holes since not the same, if the access is there some may realize there is no point. I do understand that doesn't guarantee anything but have hope.
Although, they might complain that Riot gave the a safe space. xD
But seriously, thoughts on an optional que for toxicity?
