'Elite' tier Mastery levels gated by games and KDA
Would you like to see more mastery levels that are gated by actually doing well on a champ consistently and having a game requirement? Example, mastery level 8 would require 500 games, 9 750 games and 10 1k games. Also an average KDA in your past 20 or so PVP games (to prevent being abused in bots) of say 1.5, 2.0 and 2.5 with maybe a 55% win rate minimum. And yes, if you dropped below the requirements you would demote to the lower tier of mastery, making keeping say level 10 that much more valuable. League, more so recently, feels like they have been catering to the newer/casual players. Making BE easier for new accounts, free hextech rewards, removing runes grinding etc. While I feel this is valuable I'd also like to see long term players/dedicated players catered to. Some way for us to say "hey I REALLY put time into this champ and I get results" maybe even a special champ select border/icon if you hover the a champ you had mastery level 8-10 for (for when you have a Yas one trick but you think they are gonna feed so you want to ban him anyways.)
Sincerely, a Kayn one trick with over 250 games and an average 2.79 kda over my past 23 games.
EDIT: After talking to some friends I realized that changing the system from mastery points to games played part way through was counter intuitive and would feel bad, so we decided that mastery point requirements to unlock the potential of these ranks would be better.
