Why KDA means jack shit!

As you'll see in this game, Jinx went 29-13-9, while I Twitch went 18-16-19, now who had a better game. First off adcs are what they are because of their damage. That's what's so important about having an adc their glass cannons that don't build a whole lot of defense, and are designed solely to ditch out as much damage as they can, before retreating or dying. The struggle with an adc isn't always about surviving it's about placement and knowing who can kill you, and how they're going to do it.
In this game Jinx fed at bot lane, my support was not very good and kept getting pulled by their never missing a damn pull thresh, and kept getting caught trying to harass by Jinx's snare bombs, constantly. But even though she had the most kills I did the most damage to enemy champions overall. My build adapts to different games, for example I got phantom dancer sooner than I normally would due to Jinx being fed, and putting herself in a lot of bad situations. I got Mortal Reminder because of Maokai and him focusing on me throughout the entire game and killing me often.
Point is every game is different and KDA don't mean shit, a win is a win, and a loss is a loss, but if you come out consistently have this type of game where you are getting the most damage as an adc, I have to believe that I will eventually move up.
Also on another note, I placed a total of 24 wards this game, while my support only put 10, so please for the love of God if I can place 24 wards in a game and still do the most damage there is no excuse of why people aren't warding often.
