Honestly elo hell is an idea thats not vaild {I climbed from b5-S3.} This might come off as rude, but it truly is the fact that your just as bad as the players your with. That is not to say your not a good laner, but perhaps your teamfighting is poor. Could be your warding or your missing free objectives.
Every player has things there good/bad at unless your in the lcs. There are some problems that are worse to have then others.
Did you know its often better to buy wards then items? some people say I needed all my gold for a big rod, but assumeing you had that gold you could buy a blasting wand and wards a pink and boots.
now its differnt for an adc sense BF is core, because of dragon and he has a support, but if an adc goes into lane with 75g he mad a mistake.
Now im only S3 and I know the things in this detail about where to ward when to ward, and how to position where and why, but I have flaws for example I am quick to roam. I find a lot of success with my roams in general but its costing me farm. Its the fine tuning that I need that explains why I am not a gold player, but I have an 80% win rate at s3 {last 20}
That is not to say that every game is winnable because I have lost 2 games in a row, I once lost 4 in my climb I was in bronze for a few hundred games and just started wining.
I suspect its just some issues you have that is causing you to lose.
