Mastery System in "Lower" Elo

Ill say this flat out, I'm mad. Normally I'm thrilled with my performances, but this is actually (excuse my language) fucking stupid. I'm sorry. you're telling me that a 16-1-10 Lee sin game is only an S-... First off, I'm done, thats bull, but there is a solution.

For those who aren't aware, Mastery system is based of other players in your Elo and how they performed compared to you. If you scored above i believe its 10% of the "total score" (Cs, kills, deaths assists ext.) then you get an S-. I could be wrong on my numbers but thats kinda the just of it. Why Im actually pissed is because this would have been an S (maybe S+) if people playing lee sin were actually in their elo and not playing smurfs. im teeing it.

How do we fix this? well simple. The system doesn't even have to change at all really. take the current system and add a variable to recent games on that champion. Lee sin in my case. This game is my best lee sin game to date, by far, and if i was less greedy, and didnt towerdive a cait when i didnt have flash and their naut had respawned, i would have had 0 deaths. So this game was almost 100% perfect from me, and I get an S-. if there was something there saying "You havent been doing well recently, but this game you played way better then average, lets bump up your grade for mastery reasons" This way getting level 7 lee sin wont literally take me being the most selfish person on the rift.

Simple. Bypasses "most" of the smurfs, and people can get rewarded for their performances.

Any other questions you have ill be happy to answer
