New way to deal with toxics

So I have been thinking lately on just how riot itself could deal with toxic players who affect normal players having fun. I personally just mute them most of the time, but still report and it sucks to have them regardless. I have no idea if anyone else has posted this before but riot could use a method similar to what GTAV online did where players that were bad for the community were sent to an entire other set of games. Im not saying do this after a couple offenses either, just those that have received numerous reports from a couple months straight.

Lets be honest after all, I have been playing only about 3-4 months and have met several people who say they have 7 or 8 perma banned accounts and were plat on them or something. With the way riot does it now it does suck for the person to get banned, but it sucks even harder for a new person under level 30 to get into a match with a recently banned toxic person only to be stomped on. Its punishing more on the new people than the actual toxic.

As for the other games I would say if the person showed signs of continual toxicity then to place then (in bot and normal matchs only) into an entire seperate que from non offenders so that only toxic people play against toxis. In ranked games I feel you would be unable to do this, but chat restrictions would be enough I feel. What this would do in affect is keep the toxic player from immediately making a new account, thus reducing new peoples frustrations. As well as the toxic player would still retain rank, the account, be able to play ranked matchs (with no chat,) and play normals and bots but only with other toxic players.

I know riot has measures already but what do you guys think about this? I know its not full proof, but hey its worth a shot and maybe riot will actually see this and use it. Who knows.
