Are ADC's getting unduly punished by autofill?
Since the recent change to having autofill always on, I have observed a noticeable uptick in bad or completely dysfunctional supports. It seems that a higher than normal percentage of players that get autofilled into the support role don't understand their itemization or responsibilities, creating a nightmare scenario for the poor ADC who is paired with them. This creates a negative game experience for the entire team, as the ADC will be unable to do their job in lane, making it difficult to transition into the late game power player that the team needs. This can also lead to team infighting and griefing, as fingers get pointed trying to find the reason the team is losing. I am a fairly low ELO player, kicking around silver since I started playing almost a year ago, so I can't say for sure if this is an issue at higher ELOs or if my experience is even abnormal at even my own ELO. Is this a persistent problem? If so, what can be done to fix it? Should autofill just be turned off at lower ELOs? Is there an alternative fix?
TL:DR Autofilled supports are usually worse than the people who pick support, creating a negative game experience. What can be done to fix this?
