Sorry Guys, There is no ELO Hell
There just isnt.
If you have a 5vs5 game, you are the only common factor. Over so many games (No it doenst have to be 1k games... 200 games is probably too much too)
You will reach your true elo.
Edit: Will most likely get downvoted by many silver/bronze players as most of this forum is composed of them.
