There's still hope!
It was just as I predicted, in any MMO’s there is shortage on tanks. We’re looking into add a bonus for those roles we are short on in patch 2.1.

Can you please explain some more regarding the bonus for those roles in shortage?

In the finders display it will display what roles are currently short, so if you que in with that role you’ll get exp bonus or gil bonus.

Sounds similar to blood donation. Like we’re short on blood type AB. So that’s going to show up on each DutyFinder category?

Yes it will. We are short on these people, it’s a feature we can do because we have the Armoury System.

So for EXP bonus it’s going to be like 1.1 times more?

No, I believe it will be somewhat better than 1.1 times. Also, we’re going to start random matching. Not sure if we’re going to separate the story primal battle and non-story primal battle from category but for categories are split into categories such as “Leveling Dungeon”, “End Dungeon”, “Guild Order” and if you press the “Random” button to que in, DutyFinder will automatically and randomly choose a dungeon. For those that que in with this random matching will also get a bonus. However this is once a day feature.

Once a day, what do you mean once?

The bonus you can obtain from doing it random.

I see, so you can play the random matching as much as you want in that one day, however the bonus will only apply to that first time only?

We are still looking into either making it once a day, or one bonus only. When we say bonus, it’s not experience points or gil, you will be able to obtain tokens needed to obtain gears. You will be able to obtain tokens from this random matching. Merit in doing this is that high level players will come in together with new players to fill in the roles that is short. Also we’re looking into a feature where you can submit a vote for MVP. When queuing in with random matching, players can submit a vote for another player as MVP. By collecting those MVP points you will also be able to trade with items. We are already listing up the rewards, but you can get mounts, or chocobo specific gears and such are being looked into.

Ohh, that’s nice, is that also coming in patch 2.1?

Yes we are planning to implement this in patch 2.1
