to all of the people dissenting to what I said in OP, you aren't arguing against any logical point I made, you just keep saying, "I did everything right and still lost, therefore elo hell exists."
my point remains that yes, you will play plenty of games where you do everything right tha you can, buy wards, don't die, etc. and you will still lose because of others. But the times yo win is when that is happening to the other team, and over a long number of games, it's going to happen to the other team and to yourself in a proportion that settles you in the elo that you belong at because of the consistency of how well you play (for everyone in this "elo hell" you are quick to mention the times that other lose it for you, but you know there are plenty of times when you get rocked in your own lane simply because you got outplayed, if you are say otherwise I call you a liar)
unless you can find a flaw in my argument that isn't based on anecdotal evidence "I do the right thing 99/100 games and I still lose rawr" then this also means that you might have to accept that fact that you might belong in a sub 800 elo.
One final point: the rating system is relative to the other players, meaning that a certain % of people must be in bottom % is of 1200 and below is, and statistically speaking if that's where you are right now, that's where you are going to remain unless you take steps to improve yourself instead of blaming others.
