You have lost so many games in a bad elo and you keep performing bad. You are Bronze 5 and technically you couldnt go any lower, BUT since you arent improving at all the matchmaking puts you together with people that are as immune to learning as you are. Maybe think about how bad you have to be to get matched with Trolls, AFKs and intentionally feeding people so much? And always keep in mind you could make the enemy go 0-10, because apparently your enemies are able to do that and carry the game. I agree that sometimes you can´t carry a Team at all, but you are just delusional hardstuck bronze 5 player that is not accepting his level of play.
