Champion Mastery Summoner Icons (Giving Mastery Actual Purpose)

So here is my thoughts on the mastery system... There is no actual reward you can show people without them looking at your profile Solution to this problem:- Any time a player reaches Lvl 5 mastery with a champion, give them a Summoner Icon of that Champion, so that they can finally wear their favorite champion as a badge of honor. What do you guys think? Too much to ask Riot? Just imagine now, you load up your game and during loading screen, you can just look at the champions your enemies love to play and think...

Oh bugger...
