Rewards for dedicating a lot of time to a champion

Hey fellow summoners, I was thinking about why i didn't like playing new champions and as narcissistic as this might sound, one of the reasons for that is that I'm somewhat proud for having about half a million mastery points on my main and i don't really like the idea of people seeing me being bad and not seeing that i am a somewhat competent player with other champions. So i thought it would be cool, to have an icon for every champion that you reached at least lvl 5 with and that changes depending on mastery points on that champion and of cause mastery badge lvl. Of causes some additional badges or something like that, that shows up on the loading screen in some way would be cool as well, but i would actually prefer icons.

Lemme know what you think, see you in the rift and of cause GIVE SKIN NO SKIN 3 YEARS, RITO NO F**KS ABOUT COMMUNITY REEEEE, ObNoxus
