Cannot stress how important it is to CS efficiently.

I was the 15/2 player with the mediocre CS score, but the reason my CS was so low was because I was playing Malphite Mid with Predator and roaming the entire game.

Take into account this was a 31 minute gold 4 MMR game.

Notice how the 6/7 Sivir with Double my CS pretty much had the same exact amount of gold as me, even though I nearly tripled her in kills. Same with Gragus, 8/2 with doubled my CS, had the same amount of gold as I did, despite having double his kills.

KDA means nothing if you can farm properly, you can hear that coming from a lot of pro players. "**Out play your opponent by csing more efficiently **".
