Suggestion for champ grades.

Yeah yeah, insert hard to get S rant here yada yada...

My issue with it isn't that I don't know how to get an S, but rather how far off I am. For example in my last game, I went 13/2/10, had 194 cs by 34mins and got an A. Now I'm certain it's my cs that costed me my S but I have no clue by how much or if I was faulty in some other important area.

So my suggestion is this, all relevant stats needed to achieve a grade should have stand alone grades. I should be able to go, "Ok I got an S on my kda, but a C on my cs so I should improve that!"
