When do matches become balanced/less dependent on players losing lane

Trying to decide whether I should continue or not, because high ELO games could not possibly function like low level ones. Every game somebody feeds, enemy team takes advantage and gradually grabs herald, drag, and towers, while getting fed off one player. It just seems like there's no way to redemption when someone feeds at low level, as team fights are not properly organized, and often low level players don't really understand how to organize well. At what ELO does this stop? It's a pretty horrible feeling to constantly try hard and not get tilted, to support other players and try to win games, only to go on an insane losing streak because you can't get experienced players on your team. Can someone objectively let me know if this game is even worth playing until silver/gold/plat? Seems like I'm just kicking myself in the A** to keep trying to level up to a point where there are players that won't throw games in four minutes (leading to 40 minutes of watching people on my team get 1 shot) so is it really even worth playing? Thanks to anyone who takes time to answer the poll, it's much appreciated.
