Mastery 7 as AP support
So I obtained mastery 6 a while back as
support. But since then I have yet to obtain any S ranked games, regardless of my outcome. I am constantly being smacked in the face with the letter grade A. I currently have a 67% win rate with her and a 3.2 k/d/a
My issue is that I believe I am being judge as an AP mid rather than a AP support. Yes I roam a lot. I ward and kill wards, but I feel as it is taking my cs into consideration. Why was I able to obtain S rank games and now no longer. Even in my last game in which I went 16 k/d/a I only got a letter A.
Now can Riot look into this. I see that my other teammates get lower k/d/a and still get S.
