Thankfully there are only 3, not 12.
If you can find a healer to queue with you it will likely help.
The roulette meant to fill that queue is Alliance Raid Roulette which, sadly, is currently being ilvl-cheesed to ensure people get the lower level Crystal Tower raids since people are bad/lazy and don't want to do mechanics. They're basically unequipping gear so they're below the minimum ilvl to get higher level raids (like the Ivalice series) and therefore extending queues for people who are trying to get them done.
