Nation Rewards

(Probably been thought of before, but oh well)

So, with all this hype about lore renovation, I got an inkling of an idea. Summoners could be rewarded for playing a lot of champions from the same region/city, with either an icon or a little nuance on their profile page.

For instance, I play a lot of Sejuani, but when I get mid lane I pick Anivia. It'd be cool to show that I stick with mostly Freljord champs, like a frozen themed icon or something. What do you guys think?
