S grading? I dont understand it.
So, I'm just a little bit confused on how I got an S on riven going 7/3/1 but, I don't get an S going 16/2/5. I took 4 turrets, backdoored theyre nexus, got 2 doubles and 1 triple. I had 113 cs and the game lasted 20min. They didn't surrender. Is there something I'm missing. Just wondering. (I got an A+)
