i HAVE BEEN TRYING IN RANKED GAMES TO GET RANK 7 ON 
FOREVER NOW, I LITERALLY JUST WENT 18-7-10 AND I STILL DIDN'T GET AN S, BUT FOR SOME REASON ALL THESE OTHER PLAYERS SEEM TO GET RANK 7 AND I DON'T EVEN SEE HOW WHEN THEIR SKILL CAP IS NOT EVEN CLOSE TO BEING WORTH IT! FIX THE ALGORITHM FOR GIVING OUT S AND S+ ALIKE, YOU GUYS ARE PISSING ME OFF AT THIS POINT.
It doesn't just take into account your kills. Your deaths matter too. 7 deaths is quite a lot.
Your CS also matters - you went 178 cs in a nearly 40 minute game, which is quite low, even for Kennen.
I went 28/0/19 with 214 cs in 53 minutes and got an A rank not even S- with brand. And then my last game I played I went 14/3/13 with 33 cs in 28 minutes but got a S+ rank. I played way better the first game but do you know why I got the best rank possible the 2nd game? Because in that game, I played support instead of the usual mid and I also got a quadrakill. Multikills contribute to your rank as well as your role, don't forget it.
