Lack of Rewards for 1-tricks

Since the mastery system came out its been awesome to show your mastery off to everyone to show how experienced you really are with your favorite champs, so far the mastery are great although i do believe maybe there should be more with more objectives to achieve it? Mastery 7 just seems too easy, you play 20 or so games you get a couple S's in norms/rank and you spend some ip for the blue essence. usually 20 shows you have basic understanding (mastery 5) and tbh getting 5 s's doesn't show much besides you having a couple of good games (maybe even duoing with a lvl 10 to get the free S+? ). There needs to be more reward for being consistently a great player at your champ so, more champion mastery requiring significantly more S's maybe mastery's 8,9,10 for the moment? Also on to champion mastery points, I feel like there's not enough reward or reason behind spamming a champion besides for their own enjoyment. i think there needs to be more recognition for people who spam their champs a lot such as people with over 250k score, 500k score, 750 score, and 1mil+ score. maybe an extra flair on their match load screen or maybe an exclusive skin for those with insanely high amounts of champion scores like in the mil+ because it takes an insanely long time. over a couple season to achieve a mill and i believe they should be rewarded with something. I would really enjoy to see those updates happen to the champion mastery system and please leave your opinions on what you guys think should happen with to further the system.
