S-/S/S+ rankings for mastery 7
Im really confused. Its do with with getting a S on rengar. Last time I played rengar when I sorta gave up getting Mastery 7 was when I went 25/3 got 4 drags and a baron with 170 minions at 35 mins as jg. That was only a S-. My friend tonight played rengar and went 10/3 with 1 out of 2 drags and 120 minions at 25 minutes. He got a S. Why did he get a S and I only get a S- regardless of doing better in every aspect of the game.
Edit: You guys are asking for assists, I was 25/3/6 he was 10/3/7
