please do something about surrenders and getting S+ through S-
i'm facing a issue of i cant seem to get my final S on Darius for mastery 7, i get fed, i help get every objective as in, i took two drags , rift herald and helped take 5 turrets i had about 116 cs but they surrendered the second it hit 20 minutes, the issue now presumes to be that if i get fed i snowball my team and the enemy surrenders so how do i get mastery 7 if the matches i do great in don't last long enough for me to get the crucial S ranks
