Mastery System is bullshit
The moment you make level 6 with a champion is the moment when you can say goodbye to your S ranks. I made level 6 with Alistar. Izi pizi. Got S a lot for bad scores and not too many turrets/dragons. Now trying to get 3 S for level 7. I swear to god that unless I have 78 assists at min 20 with 5 dragons and 10 turrets I can't take S. hashtagfuckeverythingandI'msaltyastheocean
