As you can see from the attached photo, I just played a game in Hexakill.
I got Grade A (12/1/15). Illaoi gets Grade A+ (11/1/19). Malph gets rewarded with an S (8/1/17).
Riot, please look into this... I like your crafting rewards system, but it frustrates me when I don't understand why I don't get a grade S for my stats.
