Ranked, And Champion Masteries.

It's pretty often you play a Ranked game where someone decides to play a new champ and test it in a ranked game. Face it... We all hate that shit. I came up with an idea where if you have at least a level 3 mastery on a champ you'd like to play, then you can play it in ranked queue. If not, then you can't. 3 might be to high, but at least a level 2.
