Idea for higher champion mastery
Mastery 1-5 goes of mastery points gained by playing a champ. Mastery 6 and 7 goes by S ranks on champs. Do you think we could get access to higher champion masteries by mixing the two systems? Let's say you get a seperate mastery points bar that only fills when you get an S- or higher. And then when that hits a certain level, then you can get champion mastery 8. And the mastery points required could be increased for further levels.
Also, I'm really hoping Riot unlocks some kind of reward system for hitting a certain mastery. I remember back when it first came out, somebody suggested unlocking champion portraits as summoner icons for champs you hit a high enough mastery with. I REALLY wish Riot would add this.
