Team Icons
I was sad when I got my tier 3 icon, and used it in-game, and realize it replaces your ability to show what mastery you have on that champion (4/5/6/7) I think it wold be cool to make it ( CRTL + 5 ) or something, so that you can still show what mastery level you are, and show what team your rooting for.
