League of Legends Grade System Concept

This doesn't expose how or why you get the final grade exactly. (cus that's not what riot wants to do so why ask them so much to do it?)
However, this does give us some form of (personal) recognition of play. Lets us see our strengths and weaknesses a little clearer. I just picked random catagories, but they could by all means be different. And maybe be different for different roles. For instance, CS isn't all that important to a JG or Supp, so maybe they would have something else in that catagory.
Please upvote if you like the idea, I would like a lot of people to see this.
Edit: Just to make things clear. This does not show the makeup of the Final Grade. It just compares your skills to other league players in your elo. To show you where you are at.
