Champion Mastery Suggestion Hub

As there's a new thread about this every day it seems, why not give all the discussion a more centralized location and keep it on the first page with upvotes to get Riot's attention? I'll start.

-Visible mastery badges in load screen. Mastery emotes are soon to be visible to opponents, so what's stopping this? -Make post-match grades visible in at least your own match history, since they're the most worthwhile thing we've gotten out of this entire system. -Alongside someone's mastery level with a champion in their profile, include an average grade. This would help separate out the grinders from the rest and give you and others a better idea of your respective strength with champions. -Some sort of reward for leveling up, whether it be chroma packs, or your champion name showing up in the load screen with the champion mastery name as a prefix (ex. Destroyer Garen), or something else. A custom emote is no real reward for the time spent.
