Please make a feature which allows us to reset Champion Mastery points

I know this post will get tons of downvote just for reading the title. But at first, I apologize for my grammatical errors, English is not my native language.

This is a common problem. A lot of people asked before to reset their mastery points. And many of you may think it's pointless, but it's not. Lets see an example: Person used to play Galio and Warwick. He even got tokens for them, but after the rework he has no idea how to play them. Or doesn't EVEN want to play them anymore, because he doesn't like their new gameplay. "But why would you remove your points you got with hard work?" Well.... I think if someone want to delete their own points, let them! And here goes another example:

Person used to play support role, but doesn't like those characters. But with a support character it's so easy to get an S rank, and that's because he got a bunch of points with them. And what is he doesn't want those characters to be displayed on his profile? It's his profile. If someone wants delete those characters from the profile they don't like, let them!

Another example: Person did not play Katarina and LeBlanc since 2015 and have no idea anymore how to play them anymore. It doesn't matter if person has Mastery level5 with them, when he didn't play them for 2 years.

Points are a good thing. But if someone wants rid of them with a certain character he doesn't play or like anymore....LET THEM!
