Why didn't I get an S or S- instead getting an A- with a 38/3/1
League of Legends Match History
I was in twisted treeline and I was dominating. I did the most damage out of both teams and got the most kills. I barely got any death and I didn't KS. I am wondering why I got an A- instead of an S and what the requirements for and S is? The details of the match is attached.
