Okay riot, what is the point of keeping autofill?

I get it, you wanna reduce queue times because they create a bad experience, but yknow what makes a worse experience? LOSING THE GAME BECAUSE NOBODY CAN PLAY SUPPORT. I cant play it, my support cant play it. Dont force us to play the least fun role so we can play more games faster, its backwards thinking when you wanna shorten queue times but just make games where we got an autofilled support a glorified leaverbuster.
