Autofill is the worst thing that RIOT has made
RIOT decided to listen to the crying community about long que times and decided to make an autofill system. Ignoring that players will get placed in a position where they have no idea how to play.
For example, you go in to a game and your mid laner is an autofilled player. Obiously he doesnt say, and he ends up going negative score and the team is overall frustrated and toxic because of this usless autofill player whos real skill is in the jungle.
Game ends, you think of reporting him but first you go to his op.gg and wuala, hes a jungle main with good score (for his rank). So instead of reporting you just decide to not do so and instead go to LOL forums to express an unpopular opinion than will most likely get downboted.
Fuck autofill, i reather wait 10 minutes or more and have a quality game than wait 1-2 minutes to have a toxic game where players are lost because they got placed in a role they didnt even picked in the first place.
