Would it help queue times if we selected all 5 roles in preferred order?
For example, I like playing support, but I feel like I can't carry games on support, so I prefer top more. I'm also learning mid, and I'm not confident in my ability to adc or jungle well. So I'd put Top>Support>Mid>Bot>Jungle, instead of just Top/Support, and sometimes autofill. Intuitively it seems like this would help the queue time issue at least a little, and alleviate the frustration with autofill.
