Champions Rank Priority

I have a behaviour about Ranked Games. As all of us know, the ranked game is the way for players to show their skills in a competitive ranking. But how League of Legends is a team game, winning a game is not only about yourself. And there comes the big problem...in every game we play, we can find a player who is trying for first time a champion, or who have a low mastery ranking with the champion selected (beeing inexperienced). And that is happeded in every division (not only in low divisions). The consequences are: ->decreasing the win rate with 23% for most of players; ->lack of cooperation between the members of the team; ->increasing of the rage quit and the gave up. So i ask if there is a posibility for next seasons, to have a restrict for champions that we are playing in ranked games depending by our mastery score with that champion. For example gold and platinum players must have >= mastery level 4 with a champion to be able to play it on rank, Diamond and higher divisions must have mastery level 5 with a champion to be able to play with it.(And that was only 1 exemple from many posibility of restrictions) I am sure that i am not the only player who think that.
