So what does it take to get an S rank on a non-support?

Your cs and warding is HORRID. This isn't call of duty.

From the look at your score and build, you'd need to:

• CS better. 121 is way too low for a 33 min game.
• Take part in the vision game, either by taking out a lot of wards (Red Trinket) or placing a lot of wards (Yellow Trinket).

High KDA is not everything in this system.

i get S on jungle all the time... even got a few S+ on him, ive even got an S on a game i had a negative kda in..

but when im on mid or support doesn't seem to matter how well i do i never get anything above "A+"

Step one: Pick Step two: Go where you please Step three: ???? Step four: Get S+

all of your stats look superb only 2 things i cant see that could have affected it is warding and many people dont know this but last hitting towers my first game or my second after champion masteries were released i got an s i may or may not have had a negative kd i know i had lots of assists and i made it a point to last hit towers i was more focusing towers than anything a d i may have last hit about 6 and im sure thats where i got my s ranked from. people dont like to admit it but kills make your kd look pretty but league of legends doesnt have a team death match mode or a free for all mode its a tower defense game. you defend your towers and take the enemies towers until you get the final objective. kd is a horrible way to try to determine skill and likely hood of winning

Its not accurate, stop thinking about it!!

Maybe it has to do with how well you did relative to how well other people did, like WoT's mastery badge. Who knows.

25 and 2 graves = A+ jimmy

37/0 Rengar with 150 cs in a 30 minute game also means A+ somehow
