How do I get an S rank?
I've done a lot of research on how I can try to better myself as a League player, and I keep trying to actively do things that players higher rank than myself do. But in this match I linked, I did everything I have read on, or thought "Man that was smart", and yet this match, even though I did exceptionally well even for my own standards, I got an A, and my cousin in the same match playing Yasuo, got an S. I am not sure what else i am not doing, or what I am doing wrong. Is there some magic factor that I am missing? Any help would be appreciated. Thanks!
