Autofill delay
Autofill. General enemy of all one-tricks. As it has been said many times being a one-trick is not a bad thing. Yet when we are faces with autofill even people who are not one-tricks themselves get upset.
Why is that? Because if you get autofilled you do not get the chance to play the champion you want nor the lane from where you are able to carry the game.
"Disable autofill then" Not so simple. The waiting times for mid-lane, top-lane and adc would get excessive and unbearable.
"Ok, give us option to enable/disable autofill if we do not feel like waiting" The same issue as before. Because most people play league only when not in a hurry and so the waiting times would not change at all for anyone compared to former comment.
"What are you suggesting then?" Give us option to say how long do you want to wait before the autofill queue starts. This will allow for shorter waiting queues as well as for people to choose how long they want to wait (+ max 2 minutes on a bad day).
