Is it me or is there something wrong with the grade you get at the end of a game?
So I've been doing pretty well in ranked today. But strangely, I haven't gotten an S on any of my games like I used to, despite me playing about as well as I used to. One game, I got 11/5/11 and another teammate got 12/5 or something along those lines, and neither of us got a S. Yet, in the same game, another teammate went 6/5/14 and got a S-. Later, I went 10/5 and got a B+, but in the next game I went 5/9 and got a B+ again.
How exactly is this happening and how are these grades decided? Is anyone else experiencing stuff like this?
