New milestones and mastery levels Idea

Hey just a few ideas I have had on how to improve the overall experience for players. I didn't know where to place them so I came here. The mastery 7 emote is cool but it doesn't show that you have actually mastered that champion, but you have had a few games where you have played well. I was thinking that you could implement new rewards for hitting certain milestones while playing a single champion. For example when you hit 500k points you get another level. Somebody with 6 million points on Ashe will have the same level 7 emote as somebody with 50k. But with this added they will have something unique to show their dedication to that champion. Also when reading how many mastery points you have on a champion I find it difficult to read exactly how many I have. The old system was much better where it would say 1.2m for example. Maybe if it had commas in the numbers and break it up.
