They are always saying and criticizing people. Im not going to claim im trapped in elo hell or anything but I will say the low skill players make it almost impossible to win most games. I win my lane, lets say solo or top 90% of the time. out of 20 ranked I solo lane 2 times with an averga KD of 3-1 and higher cs. most of my games end X-6(+). A high level player will see the 6 deaths say I was the reason I lost and call it good.

Why this is bad logic.
Bot feeds lets say 5-6 kills to adc carry before 15 mins. all bot has to do is come mid after a kill, I dot care how far back I am in my turret. If 3 people (4 w/jungle) want me dead, im dead. If I yell at my teammates to help me mid and they refuse by taking the farm bot since they can breathe for a second, theres nothing I can do. Or if a lane is bad and the jungle focuses me. Im stuck in a 2v1 for a majority of the game, if lee sin wants to dive me and shield out to his mid buddy who is bursting me down and im not getting help, theres nothing I can do.

Then mid-late game when now my lane is fed from getting camped, all the other lanes have done a good job at that too, my score starts going downhill. If my teammates fed and keep saying "PUSH" then make it halfway to lane before getting slaughtered I have 2 choices
1. Go in and pray a miracle happens
2. Stay back, not die, but have no team impact whatsoever
---- I chose 1., why? it at least gives a chance of something happening instead of my team dying then a 5v1.
Problem is the low skill players dont understand passive play when down or they dont know how to setup a good gank or strategize a way back. This may sound generic but it is 75% of my games now. I do nothing wrong, I know how to wait for a winning teamfight opening but its a team game and if 3/5ths of the team doesnt know how to properly play, the odds for the other 2/5 are low.

Understand this High Elo players. You got lucky and then proved yourself to stay on top. If your first 5 ranked games were loses from you being the only positive player on your team, you might not be where you are.

Tell me my faults, I dare you

Well, just from your example, aight.

1) Your exact words were "I won my lane." Good for you. Well done, too bad the other lanes lost. Too bad you couldn't, well winning your lane, leave lane and go down to bot kill or force the enemy adc and support out of lane, alleviating some of the pressure on bot and helping them get back into the game, and maybe even pick up a kill yourself. Then head back to top, which you've been winning, and your opponent will likely now have caught up with you (because you were winning and they were behind)

2) No, if 4 people want you dead you are not dead. Or, at least not where it was worth getting you. These's these fancy little items called wards. And if you want to win and you are destroying people, you'd better expect the enemy to want you dead. So you'd better have these handy little items down in the river, and probably in the entrances to your jungle. NOW YOU CAN SEE 3-4 people coming to kill you and you can not be there! Or, you can now make it so that you trade 1-2 people for you. This was not a good trade for them. And then you TELL the other lanes, in no uncertain terms, TO PUSH. Get 2 kills and 1-2 turrets for the price of you and one turret.

High ELO players are not lucky. Wingsofdeath lost 4-6 of his placement matches when S3 hit and, guess what, he's Plat now. And you know what? He really didn't care he lost those games. He even said he didn't care. High ELO players have the KNOWLEDGE to consistently win until they are at the ELO they belong at and the SKILL to apply that knowledge.

im 1200, which is far from high elo, but i can confirm that u r wrong to believe in elo hell, blaming ur teammates is counter productive, meaning that it hurts rather then helps.

I just played a game as Teemo top. Every lane but mine fed. Every single one. The jungle fed, mid fed, bot fed. Then our adc went afk.

I had 4 kills top, 1 death (tower dove, but I should've avoided it, stupid me) and I had the only kills on the team (I think our jungle got 1 assist). Their team had 7-10 kills at this point.

This is where you would 'pray for a miracle' and start blaming your team for the upcoming loss. Instead, I ventured down to mid and saw their team getting ready to push down the lane. I positioned myself in stealth behind them and once they engaged I took out the 2 carries from behind and escaped. Team fight won.

After that, we had 2 or 3 team fights where clever mushroom placement and good use of Teemo's passive lead to use winning each time while only losing 1 or 2 people. Our ADC, Varus, had been going afk randomly for 2-3 minutes at a time, coming back only to charge down bot lane and die.. after seeing us winning team fights, he starts to play again.

Fast forward 20 minutes or so and the surrender vote goes in. We win.

Sure, their team could've bought oracles sooner or focused better to not lose, but the fact is that they didn't. They got cocky because of how far ahead they were and allowed our team to rally after a few good fights.

This is just a single example of how 1 player can turn a game around despite feeders and afkers. I can't claim to be high elo nor can I say I'm that great of a player, but someone who is both of those can certainly make a large difference in a game despite how poorly their team may perform.
