So I am trying to reach mastery 7 on Caitlyn (just in time for the prestige skin lol), and I always had difficulty in earning S grades on her but I somehow managed to get to mastery 6. Right now, it feels nearly impossible to earn S grades on her even when I feel like I am doing relatively well.
Take this match for example: https://matchhistory.euw.leagueoflegends.com/en/#match-details/EUW1/4104824227/2075892462882752?tab=stats
-10 kills, 16 assists, no deaths
-212 cs (most in the match)
-Most damage dealt
-Placed 15 wards, destroyed 5, and purchased 4 control wards
-Earned most gold
And I only got an A+ on that game, I am so confused.
