Interesting numbers (KDA isn't the end-all factor in winning or losing)

A recent discussion led me to find these numbers in defense of my item builds and selfless play style. I have a keen tactical mind, but my mechanics aren't great and haven't gotten much better over the course of five years or so. Therefore, I tend to play it cerebral - luring opponents where I want them to be, forcing cooldowns in teamfights through "Destroyer Tank" tactics that use one's mental reflex to jump on, highly mobile champions first against them, and so on - and make selfless plays that facilitate my team's success, rather than trying and failing to be the hero myself. My primary goal in any game is to facilitate my teammates and give them every opportunity to look amazing. It works.
As you can see, in many of my wins - and my overall win rate is rather high, jungle notwithstanding - two or more of my teammates have an extremely high KDA as a result of my low KDA. People would suggest I was carried, sure, but these people are consistently in my same tier of competition. Further, it's not as though our opponents are unskilled. The matchmaking is solid, and our opponents match us in every game. And this is putting aside the fact that being carried in 11 out of 12 wins, as someone suggested in another thread, is simply implausible.
And so, I submit to you with clarity and certainty, that play style is a legitimate difference between players that can be effective in winning games. Wins and losses are what matter, and however you have to build, whatever personal strengths your play style has to play to, to make that happen... It's viable. Ideally a League player is equally good at everything, but let's not gate the game here. There is absolutely a place for those who do one thing really well, so long as they understand how best to apply it for the team's benefit.
