Milestone system to Champions

TL;DR: Implement a milestone system for each champion before being able to pick them into ranked. Should help raise the bar on the game and lessen the smurfing issue.

So ive tried having the support division suggest this to the Dev team but that doesnt seem to be working so ill be saying it here. Please Implement a Milestone System for Ranked. See, I dont think that just unlocking champions is enough to allow players to be able to play them in Ranked. Rather, I'd like to see them at least get a border with a champion before being able to play that in a Ranked game. That way they KNOW how to play the champion so they can not screw over other's games with their unnecessary risk-taking decisions. On to the suggestion, Id like a certain Milestone to be set for each champion before being able to choose them for ranked. I don't mind the problem with people having at least 16 champions played to a certain milestone before being able to pick them in Ranked. This should also make smurfing harder for people. Why? Of course players are going to have to play that champion over and over again before being able to unlock them in ranked. This means that buying them right of the bat just because you've mastered them in an alternative account would not suffice and thus would have to grind their way up again before being able to 'smurf' on their 'alternative' account. If there is a reason why this cannot be implemented I would like to receive an acceptable explanation because from my point of view this seems to be a very beneficial feature to add into League of Legends.
