This has to stop

I am so sick of losing lp because of mistakes my teammates make. I don’t like blaming my team and I normally try to figure out what I can improve on after a loss but today has been insane. I had 2 games where my adc and support said gg and left before 5 mins, another game where my mid ran it down the whole game, and finally a game where my whole team go fed but they kept picking bad fights even though I kept pinging them away from the fights. Something needs to change because I want to rank up and get better at the game but I can’t do that when I get screwed by my teammates 4 games in a row.
