autofill protection is essentially useless for adc and support mains
If you are bot lane or support main, it doesn't matter if you have autofill protection. Your lane is dependent on working with someone else who may be autofilled. I get it. There are no easy solutions for this. Honestly though, as programmers you don't get paid to implement easy solutions all the time. Sometimes you have to come up with a complex solution that makes the game better for everyone and not just the top/mid/jungle mains.
Yes, I know you can get a duo to play with you. No, that is not relevant to this discussion.
