Perfect S+ Guide
The guide to get an S on every lane: for top lane it's minimum of 200 CS, for mid 250 CS, for jungler about 150-170 (depending on the duration of the game), support 45 CS (if you wanna make sure to get the S) and finally ADC is about 300-350 CS (depending on the duration on the game)
For KDA, it's most of the time (not for support, but i'll talk about it later) 10 kills minimum and 2 deaths Maximum, and assists are about 3 times less important than kills (for laner), so for supports, its about 2 deaths maximum for a minimum of 15 assists, kills also count on the KDA, but don't think they count more than assists, they have the same ratio for supports.
And one last tip, you need to buy a minimum of 3 pink wards, but don't just buy 3 and places them one by one, it won't work, you need for your ward to last a minimum of at least 2 minutes.
Example :
i'm a top laner, and i am 12/2/5, with **237 CS ** at 32:21 minutes, and i placed a total of**_ 4 control wards_**, and destroyed 2 towers : S+ guaranted (btw, kill steals don't have any effects, i've tested that a lot when playing jungle, but don't be anoying and perma-steal kills ;D ).
PS : i've tested a LOT of champs to get to this perfect conclusion, you can trust this , 99.9% confirmed (in about 150 games, i've made this statistics)
Good luck ! [slayer-pantheon-thumbs]
By the way, it's not a guide to make sure you get the S, it's just showing you the conditions to have them ! SO if you want an S, just play correctly and respect those conditions .
