Cs and KDA are toxic metrics
Cs and KDA are toxic and useless statistics for league. It stands to reason that since power comes from items purchased via gold that gold earned is more useful. Cs is toxic mainly due to the discrepancies between Cs value between the jungle and lanes. One full clear can be accomplished in the same time as 5 waves of creeps. 1 clear is 19 Cs worth 422 gold. 5 waves of Cs presuming 100% accuracy is 583 gold at 31 Cs. Thus the jungle is worth 3 gold per Cs more than creeps on average. That's not the problem, what is though is how both share the same statistics in game. Switching to gold accumulated would normalize the information and is more relevant to game objectives.
