Did I play badly and got a B? No problem, B for me.
Did I play average and got an A? No problem, A for me.
Did I play well and deserve an S? Oops! Game broke! Again! After 3 months happening!
I swear to God Riot, I suspect that this bug is left on purpose so we have to grind even more for a Mastery 7.
I only play to get Mastery 7 on certain champions AND I CAN'T because the game MAGICALLY BREAKS every time I'm gonna get an S.
And I KNEW it was going to happen as I was playing the game, I KNEW I was gonna get NO MASTERY... A G A I N.
MONTHS happening, MONTHS! Nobody answers, nobody addresses the problem, not a single answer or compensation. They do not care.
Honestly, I should get all my mastery points, it's not like I'm asking for money or skins.
