This happens to people in every elo. That is why "elo hell" was created as a term to describe this situation when it happens to a player REGULARLY. And yet high ranked players who complain about having this in their games all the time and being held back from wins by 4 bonobo feeding teammates will claim not a single person in bronze, silver, gold (diamond - if they are plat or challenger or master) knows ANYTHING about the game and deserves to be where they are. Cuz yeah only (insert player's rank here) or higher can possibly understand anything about the game or be held back by regularly getting teammates who don't have the skill or intelligence to be in a game with them while all their opponents do. And posts like yours will do nothing about it but get you grief... trust me, I know from experience. The difference with your rank vs truly low elo/rank is that at your elo people still have some basic knowledge of macro play... while at low elo, someone stuck in a similar "elo hell" experience can know and shotcall exactly what to do to (what someone at your elo would call) and looks like an idiot for doing it because no one listens and they chase their tails losing objectives while the one guy making the correct call gets punished for doing the ONLY play that gives his/her team a chance to come back and win.
Ex: option to collapse on enemy 2 man split push too late to save tower and: trade tier 1 towers but lose drag (team chooses this option) or... option 2: listen to the jungler who is the whole reason your top and mid are fed (your bot still fed for no reason 2v2), tower dive mid inner to get tier 2 tower, up to 3 kills for prob 1 death, and get infernal drag. Which is the better call? Trading towers and losing infernal or grabbing INNER tower, maybe kill trade advantage as well, and getting drag? Pretty sure option 2 is way better, but you can't make your team realize this. And telling them later in chat when you have a chance to safely type just gets "reported" from your team. So be grateful you have more intelligent teammates than this even if they are worse than their opponents.
