Riot wants to make an Auto Fill if your Queue is too long

Basically if your queue timer is too long where your primary and secondary hasn't been picked, you will automatically have a "FILL" as primary. What would this mean for the future? MORE SUPPORT ROLES.

I watch a lot of high elo streamers and noticed how long they wait, there queue can last about 30 mins or more.

It's an obvious reason for it to be that long because there isn't much players in that kind of elo, they haven't made it that far ya know?

but on the subject I find it absurd to be forced into a role that you'll LIKELY fail at even if the chances of you getting support is super high.
