Getting an S

I really do not think that whatever the mystical system that grades us works to its fullest potential. I am not amazing at my favorite champ: Lux, but I also have games where I do really well. I do not feel rewarded after such games from the grade system because I do not receive an S. I think the grading system needs to be looked at in order to make players feel as if they did do well, when they do well.
