I have no control over the outcome of my games
i play

I really feel like I have absolutely no control over the outcome of the game. I don't play to climb but rather to better myself. But how am I supposed to carry when in low elo people tend to hard feed instead of playing safe after a couple of deaths and when riot just buffed the hell out of snowballing? So i just shrug off games where it's a stomp (on both sides, i don't' like being carried as much as i hate hard losing a game) But that's the problem, win or lose, i feel like i have no control. I read a post where they said that 40% of games are a win, 40% are a loss, and 20% you have control over and you decide the outcome of the game. but that's the problem, I haven't had one of these games in a long time. I know i still have a lot to learn, but how am i supposed to do that when i have no room for agency in my games?
