Tips for S rank
Can anybody give me any tips for getting S rank, I still haven't got one. My friend says he has gotten some as Shyvana going like 20/4, but I play Fizz going 24/0, and no S, I play Kennen, carry my team, 32/2, somebody says to me "congrats on the S" and after the game, A+. Should I just main one champion, I don't have a Mastery 5 yet
