Stupid Grading/Mastery System
So I need 1 more S for my mastery 7 with Ahri but no matter how well I do I cant seem to get it. I have noticed that getting an S with most mid champs is extremely difficult. I can go Morgana support and get an S or S+ easily as well as my ADC. But after this last game I had at 27 min with 24/1/3 and they give me an A+. Seriously?
The past two times I got an S I did far worse in a longer game. I cannot understand how this grading system works since kills/damage don't seem to help much. From what I can see I get a random grade somewhere around an A. This is very frustrating seeing as how this terrible system is the only way to get mastery level ups.
