How to get an S grade?
I really have no clue how to get an S+, S or S- grade, I had a 37/4/4 match with Tryndamere and 212 CS, and I got an A+. I had another game with Tryndamere, this time 32/2/4 with 141 CS, but only A+, today I had another game with Tryndamere 17/0/2 with 89 CS, this time I got an A. (I won all the games ofc) But does anyone know how to get an S- with Tryndamere, if so please reply. :)

This made be so
