Anytime people start using their feelings as reasoning or an excuse for why they are where they are, they may as well be dismissed. There is insane amounts of evidence that 'elo hell' doesn't exist, and that the vast, vast, vast, vast majority (I forget the statistic but it's over 99%) of players are where they're supposed to be or on their way to it. Arguing against that is like arguing that masturbation is a sin because you think god said it is. You can say it all you want but it doesn't make it true.
At low ELO, game knowledge and decision making are probably more important than mechanical skill. Mechanical skill can win you small fights in your lane, but knowledge and good decisions will win fights for your team all across the map. Knowing when to push, when to back, when to roam, when to follow, where to ward, WHEN to ward, etc. are all HUGE. People think they know this stuff, but it gets fuzzy and lost a lot when actually in-game. We can all watch the LCS and boggle at bad calls, but when presented with dozens of opportunities for making plays in-game, most people in bronze/silver won't even notice and just let the other team do whatever they were doing.
The reason I don't like jungling is because it is CONSTANT decision making and timing is literally everything for a jungler. I'm really good at map awareness and roaming/helping my team when I'm mid/top, but when I'm in the jungle it's just a different world and gets a bit overwhelming. Even when I get stuck with support (which I'm also not great at), if me and the ADC are winning our lane I'll constantly be looking at mid and our jungle for a chance for me to go help and just let the ADC farm more (or follow if he wants).
Edit: waaarrrrdddddssss. Unless I'm ADC or Jungler, I start the game with at least 1 ward. Every time I back, I buy at least 1 ward (unless a HUGE buy prevents me but gives me an advantage anyway). I can't even count, over the past dozen or so games, how much gold those wards have prevented the enemy team from getting and enabled my team to get. It's not even just for your lane, if you're top and you see the jungler come for you, you back off and make him wait there and get your team to act on it. They won't always obviously, but they will often enough to fucking matter.
