Here is what happened last game I went 9-1-2 on katarina 119 farm in a 20 minute game and got A+ A lucian went 9-1-6 106 farm and got A-!!!! A taric went 1-0-13!!!!! and got an A as well............ Riot what the hell is wrong with your system i went 13-11 on shyvana before and got an A+ and this score on katarina is the same to 13-11 on shyvana?
its based on more than just YOUR KDA, it evaluates u against all the other people's scores in your regon and if u have one of the better scores u get an s
That's not how it works. There are some good explanations online, although I still haven't found one good enough for my OCD abatement.
Basically, it works like this:
Your score is compared to other people who played the same champion in the same role. So if you played Katarina Mid, you were compared to other Katarina Mids, not Lucian Bot or Taric Support.
It compares all stats, so minion score is also important.
The part I hate is that the S appears to a moving target. For example, I got a few S ranks on Zac even just a month ago, but now it's harder to do. I've had better games recently without getting an S, which is frustrating since I only need one more S to get Rank 6 Mastery with him.
If you buy a pink ward it helps a lot. I havent gotten an S a game i didnt buy at least one
