Why is auto-fill still enabled in ranked?
Serious question that is probably never going to get an answer, let alone any sort of statistic showing that it's beneficial.
I just had to sit through an auto-filled support Morgana maxing W and pushing with it on cooldown, in a game where we had a funneling mid lane (aka no jungle), leaving us constantly open to ganks with no possibility of counter ganks.
This feature has no place in ranked and does absolutely nothing positive for the game. It should have been removed long ago.
