Mastered Champions Slot

Hey everyone, I love the new mastery thing with champions and i love how it shows the top 3, which are sometimes the mains of players in league, but i want to show off all the champs i have mastered not just the top 3, so i thought what if riot made another slot in your profile showing all of your mastered champions. That way other players could see who else you could do well with in game, and see what kind of champs you like to play.
