I am a diamond 2 player with master +/- mmr and almost 50% is going the same,you either lose cause you have a teammate who is playing dogshit because he is autofilled, or you win because the enemy has autofilled players.
It pretty much says itself that a master adc wont perform as good as a master toplaner.
Riot implemented "autofill" to shorter the queue times, but honestly id rather wait 5+ more minutes than playing a 30min game beeing autofilled.
Today ive played 3 games and autofilled in 2 of them (lost both autofill and won where i got my role).
I also dodged cause i got autofilled only to get in a new lobby where i am autofilled.
Please let me know how you are feeling about the ranked system as it stands now.
