I have found out the truth about autofill troll/feeders

Back then the system was pick order=role priority, meaning if you are a earlier pick you get to have whatever role you want.

At that time, a group of players exist, they are the champion select trolls. "mid or feed", instalock, Taking a role someone higher already took, etc.

The people who now whin in your game about getting autofilled and then troll are just the same people.
