S mastery for jungler...

In this game, I jungle. I get first blood I stole enemy blue at start by warding enemy camp and smite-steal I have the highest kill participation (63%) I have the most kills I have a good KDA (12/4/12) I secured all dragons and all baron nashor I am 2nd in ward placed (after our support) I did good dmg to champ and tanked and cc
All my teammates got an S or S+, except me, I had an A+. Because I did not CS enough, I guess. You know why? Because I don't steal cs from my laners, and because I ganked and controlled objectives, I did not power farm the jungle.
I don't complain, but for logic, I think this should be fixed... it makes no sense.
