Ok so I had two awesome games today as 
that I won both of
first one I went 9/1/4 and 85 CS and got an S and my first mastery 7 token for her, so I'm happy there
But, this annoys me,
my very next game I went 22/3/7 and 165 CS still on and got only an A
So please if anyone can explain that logic please try. My Jinx is crying because she deserves mastery 7 on my account
It's heavily effected by how long a match lasts.
Length of match time, kill participation, and deaths have effect on score. If the second game was substantially longer and you participated in less kills by percentage overall, then you likely get a worse score. Also, if the game was REALLY long, 165 cs is pretty poor.
That and you died three times.
Your cs isn't good for that length of game, especially as Jinx. That's probably why
First game was 18 minutes. Second game was 38 minutes. Not hard to figure out
I feel like you should have gotten a S cause you had double the cs/creep count and kills/assist and im sure the match was way longer since u hade more kills the second round the facts point that you should have gotten that S but you didn't get an S makes me feel like a normal person sorry you didn't get that S bud
I understand the cs was low for a longer game, but why is this post getting downvoted? It's literally just a question.
The game was about twice as long, and while I should have had a bit more CS, I feel that after I participated heavily in all the team fights I could (few exceptions where they were on the opposite side of the map, but that happens), I should have still gotten the S. And I understand that it is supposed to be challenging, but I have been trying to get a single S on jinx since I've had her at mastery 6 for quite awhile now, I think 7 months sounds about right, without even an S-. this seems to be quite unfair considering I have also had several games where my CS was much higher, and my KDA was very similar if not better but I have still always been denied an S but a 9/1/4 game with 85 CS can earn an S.
And I read a comment that said that my total participation in the overall kills counts too, in response I'm just telling you guys that the team I was on had 65 kills in the second game, so I held a solid 1/3 of the entire teams kills.
Sorry if this sounds like a rant, but I hope ou all understand my feelings on this, thank you for the comments, good and bad so far, nice to know that I'm not for all apperances shouting at a wall
165 cs is weak A F
It appears that CS is the most important factor for calculating those scores.
I've played games where I've done everything, been in every fight, secured objectives, had tons of kills and assists, really high kill participation, few deaths, and only got A.
I've had games where I did nothing much except farm, was hardly involved in any fights, picked up a few kills and assists here and there, but had a high CS score and got S.
