Riot focuses too heavily on Creep Score for Mastery Rating
Here is a link to the average CS a person needs to level up Via CSing

Meanwhile 1 Champion kill = 50% of experience towards your next level
So why is it that Champion kills are so insignificant compared to Creep Score To Achieve higher mastery ratings when you gain a larger amount of experience for kills
I Get that Creep Score is also a skill factor and that Players who can CS better will often get higher scores, but it seems that at this point, you wont get an S (even if you have a very good KDA) unless you have around 250+ CS
I literally had a Poppy on my team go 4/7/6 but she had 340 CS so that somehow earns her an S even though her KDA was pretty poor
Riot is Promoting AFK farming too much with this method, poppy could farm all game and not teamfight but could still get a better score than the rest of us that got kills and objectives.
I feel like CSing relates more to personal skill and not champion-related skill so why should it have such a large effect on Champion Mastery?
