No such thing as ELO hell and the simple reason is that you have evidence in every player who have climbed out of the supposed ELO hell. And to compare it to higher ELO ranks when talking about feeding and such?
EVERY GAME has a team that loses. In both winning and losing teams, some might do very well and some might have fed. Just because someone goes 0/5 does not make them trolls or intentional feeders. It just means they either made a mistake that the enemy capitalized on or that their opposing laner is significantly better in skill.
The reason why ELO hell doesn't exist is because ELO hell means no matter how skilled you are, your terrible lack of skilled teammates will prevent you from ever winning enough games to rank up. The pros and higher ranked players who CONSISTENTLY play well can climb out with ease. Note the CONSISTENTLY is capitalized because this is essentially what solo queue rank focuses on. If you play consistently well, it will increase your chances of rising in ranks. For example, let's say you go 10/0/5 every game in a generally low kill/death match. Now the chances of you winning when you are playing this well is high. I'm not saying it's definite, you can still lose many games with such kda ratio and your stats don't define how great you are. This is where, once again, consistency comes into play. If you are consistently getting 10/0/5 every game, even if you lose, you contribute that much more to winning each and every game.
Now, your KDA individually doesn't mean squat. Gradually as you play more and more games, you will accumulate a KDA average and a rank that seems to fit your skill level. THIS is when the consistency of KDA is important because it differentiates between whether or not you are the feeder or if you are leading/carrying games. Now, if you only have 3 ranked games in your history, your KDA won't mean ****.
Another thing I want to point out is that you seem to think, or you are coming off as if you think that higher ELO players ALL play well. Like I said earlier, there is a losing side in every game. 0/3/0 in higher ELo can be comparable to low ELO's 0/10/0 as higher ELO players can capitalize on mistakes better and have better general knowledge of the game... but you are assuming too much. Even pros will "feed" like crazy. And you guys have the wrong definition of what trolling is.
If you want to see a real troll in LoL, it's the Teemo that goes to Baron at lvl 1 and sits there as a vision ward for 20 minutes; not even afking. Trolling is Anivia intentionally walling their own teammates from escape/danger. Trolling is picking Trundle and using your pillar to screw over your teammates. Another pro trolling is doing your normal combo as Elise and when you press E to Rappel in when your jungler ganks, don't Rappel in and let jungler tower dive solo and die. Those are trolling. And these are all done intentionally. There's a difference between players who just suck and trolls. You can't try to accuse ****ty players of being trolls or feeders when it is not their intention to do so.
I can't tell you how many times people rage NOT EVEN IN RANKED! IN NORMALS! And it would be the stupidest thing. This premade 4 group where top, mid and bot lane all fed. I was the jungler and all of them constantly *****ed at me. I made decent plays to help them escape and get kills but I never would get credit for it. They would just keep typing in all chat, "This jungler sucks, report for intentional feeding." My score was 2/8/8 at the end while I started with 1/0/4 until mid-late game. When you come across people like that, don't say anything back. These people are just retarded; you just mute them and report them. The end. Don't concern yourself with trolls at all either. So the things you have to worry abuot in ranked are mostly ragers and unskilled teammates. The rarer part is the trolls and afkers.
