Just played 
in order to get my level 7 on her, By the time the game hit 15 and the enemy team surrendered I was 21/0/2 AT 15 MINUTES.
I HAD 88 FARM.
do you know what score I got?
S-
S fucking minus.
THE FUCK YOU MEAN I GOT AN S- WHAT IS THIS BULLSHIT
not enough farm...and maybe not enough vision or objective participation. their specifications are really strict tbh :/ im trying to get M7 irelia jg, but that aone is hard as fuck
edit: yeah you have zero vision at all. So MY belief why you got a S- is you had 0 vision score, and your CS was not enough (MF had 93, so you had to beat her CS and outfarm her to get a S i believe) Your objective participation (turrets) was pretty good, but you lacked in the CS and the vision.
The rating system, to be honest, rates farm perhaps SLIGHTLY too high on a performance. If you NEVER die and have that many kills, you probably deserve an S.
