Mastery Points Milestones

Hello there, I really don't know how the Boards work, the support staff told me to come here. Here is a bit of background, recently I got 1 million champion points on a champion (GangPlank), and just like me, other players got 1 million + points on their favorite champion/s. And the fact of investing so must time and passion on that specific champion to get those high numbers is already rewarding, in my case, I passed the last 2/3 years playing GangPlank, (of course not constantly play him, but for a good part of that time focusing and learning his kind of playstyle, his best matchups, his weakness, etc) and I think we should get some kind of reward. I understand the fact that the game has 140+ champions and with the constant reworks and putting new champions is for the player not get tired of the same champions and mechanics, and I totally agree with that. I will repeat myself, but I think for those players that invest so much on the champion that they love, they should get some kind of reward. At least at the end of the game that puts that champion on those big numbers a popup/message congratulating him, just like when we level up or finish the event missions or even an end season reward.

I want to know what you guys think of my idea.

Thank you for your attention.
