Getting an S is easy for most champions but some seem impossible
I go 16/3/7 in a game playing as pantheon and I only get an A-. I play Yasuo and get a score of 6/1/2 and I get a S/S-. Recently I also played a game as Teemo and got 11/1/4 and got an A- whilst the Nasus on my team got 3/6/13 Got an S. . . Why does this happen?
