Put Mid > Top, got top. Mid laner says he put Top > Mid

I also have had this occur.

Sometimes the person originally wanting Mid hints at that in champ select by showing champ. And then I just ask them if they would rather Mid and they say yes, and proceed to tell me they picked mid.

So I am not sure how the system works. Unless it is filling roles along the way just like team builder but it's behind the scenes.

But still not sure how that priority works. If @Riot actually gave us a sound algorithim with how it works and why there are so many kinks in the system including queue times and role duplication NOT including 5 man pre-made.

I put Support/Mid and got mid. As solo Player with a premade of 4. That's something I haven't seen before.

the system is broken

i had one game where 4 people got their secondary and their primary roles were taken by others with that role as secondary choice.
