The amount an s rank puts on cs

honestly after playing several matches i noticed that the score of your game relies heavily on cs even if you are a jgler. while i think it matter alot if your playing top, mid or adc junglers should not have so much leveled against cs, for example if you get all 5 drags and baron, then have a great kda with an average cs you should get an s as a jungler. you've been helpful all game and shown your role wonderfully yet because you don't have the cs to match you don't get the rank you deserve.
