Which role will make queue times faster?

fill.

But you are in the top 83% of players on your server.

So 83% of the population of your server plays in or near your elo.

I doubt u have 4 minute ranked waits for supp/adc queue. (unless your OCE server is extremely underpopulated, in which case sorry for assuming)

support would always give you quickest Q time. Server population will affect that too though.

The games is losing its popularity, so que time are going up

Support or auto fill support use to be instant instant

yeah around 3 min mark as support and adc

i decided to try top and support and time is indeed 4+

Fill primary will get you the absolute fastest queue time possible for your MMR.
