Queue Prioritization - How Does It Work?

[Risvertasashi]

So, unless you miraculously get a full party all directly queuing for that instance.

Really, there's a pretty decent chance this will happen in, for example, stormblood leveling dungeons... which can mean shorter queues for DPS. Queues are harsher for things like story trials (no reason to queue them more than once, so you rely on the roulette a lot more), or things like the 50/60 dungeon queue, which... once again, no one queues for individually and even the roulette is slow.
