Can we have dynamic queue matchmaking prefer roles for players with higher champ mastery points?

I was thinking that this would be a great way to discourage players first-timing champions in ranked. People are always complaining now about how they are always getting secondary roles so often (especially if you pick support or fill as secondary). If you are a dedicated main for example, you would have a much higher chance of getting the "top" slot than someone who locks in a champion they have had little to no experience with in normals or ranked.

I think this way you would ensure that the player is experienced with the champion they are playing. This doesn't enforce a meta in anyway as you can have a high mastery with any champion but it encourages players to practice on one guy so they can be successful in ranked.

I also think this would be a cool little bonus for people with champion mastery since all we have now is the badge that people spam to BM other players... let's make it practical.
