What you are suggesting is illogical. People that have 200 games played can be better than the ones with 1,000 played. Do you know why ? Some people are better at some things than others. You can have 4,000 games played and still be bad because there are people that never learn and never will be able to learn.
Also if you are gonna play ranked, you gotta be dumb enough to go and play champion that you only played once or twice before. There will always be trolls/afkers but you gotta see that even in 4v5 you can make a change, carry a team, put your best effort into it and never give up.
Just my 2 cents, i might be right i might be wrong but who cares, i'm just another random person trying to explain some **** on yet another "ELO Hell" thread.
