The reason why ELO Hell Exists
It isn't that players are so god awful that you can't win - because you can. You can literally tell your team exactly what to do and how to play to win. Even if they are bad players it does not matter you can still win.
The reason that ELO hell exists however, and why some games are unwinnable are because of pig headed teenagers and 20 some odd yeared man children. Take for instance my experience. I main support and jungle. I have been in silver since season 2 and been to 31 promos. In silver I fly thorugh 5-1 no matter what and get stuck @ promos and then usually have a huge losing streak because mmr matches me with a "certain" kind of player once I reach too high without crossing the streams.
There is no game you cannot come back from even if your team is bad - they key is that they just need to listen to the guy who knows hat I am doing. I have over 1k games as support, not as many as jungle but playing these roles - I know macro strategy. I know how to win games. When we have an advantage - I am shouting to my team "GROUP 5". When we are down - "Defend 4 ward objectives player X split push for us and ward up so you don't get caught".
I am no pro but the tiny nuances of when and what to do I do know pretty well. Even if we are behind I can speak about a strategy that will win us the game - it has been out long enough and simple enough it isn't hard to do. What really makes ELO hell a reality however is that MOST PLAYERS IN SILVER AND GOLD DO NOT DO THE CORRECT THINGS TO WIN, AND IGNORE AND TROLL THE PLAYERS TRYING TO TELL THEM WHAT TO DO.
If a guy knows what he is ding and says- we are ahead by x we need to group. Please listen to him next time in your games. That is really the difference between winning and losing. Even if its the wrong call its still a call. If you all do the same thing then it most times works out instead of each player doing his own thing. PLEASE LISTEN!!
