Champion Mastery Idea

I think it'd be cool if there were a certain icon when you're loading in when you're playing the champion that you have the HIGHEST amount of champion mastery for.

I think it'd be nice if we're all loading in and I can see "Oh, this guy mains champion X, he or she probably knows a thing or two about using them."

I say this because in a year, champion mastery will mean nothing. Everyone will have a tun of champions "Mastered," and it'd be cool if people could recognize I'm playing my main.
