UNIQUE CHAMPION ACHIEVEMENTS!!!

Playing a champion proficiently in a certain way isn't really rewarded a lot. Perhaps recognition for being able to pull off an AP Shaco or a Dash stopping Thresh should become a thing or summoners. My suggestion is to give rewards and champion Achievements for not only being dedicated and skilled with a champion, but being able to play a champion in a certain way. Rewards should be summoner icons that reflect the certain (some would say planned or calculated) playstyle/champion role that a player is dedicated to and skilled at. Rewards should only be obtainable when a champion is already mastery 4 or higher to avoid trolling or just being considered bad.

Example:

Shaco: Champion Achievements
