What would I need to do to move from an A+ to a S?
In this game here: http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/2312951524/212289088 I was able to go 10/1 with Kog'Maw with decent CS (180 @ 30 minutes) but I got an A+. I've really been trying to get S ranks on him so I can get level 7 on my Koggy. What would I need to improve on in order to push myself over the A+ line into the S rank range?
