Difficulty setting on norms?

I think Riot should make a difficulty setting. Meaning by having difficulties such as easy, average, and challenged. And these difficulties will depend who you get matched with. However if you picked challenged but you end up not doing so well in challenged a system like the tribunal automated system can disable your option from picking challenged for a certain amount of games depending on your champion score (S,A,B,C,D aka mastery thingymajig) However if someone picks easy and they're challenjour just wanting wins they can be disabled from the option according to their match history. This is just an idea I had in mind, I know that I'm not clear but guy please write suggestions if your wanting this to happen or something like this..

p.s. this was a idea I had in mind because people are either to good or bad at the game and wanna be matched with their skills. I just feel the current matchmaking isn't good.
