If BST becomes a non-limited job, it'll probably be a melee maiming job since we just got a ranged DPS.

Chances are, because SE is moving away from pet classes for SMN and SCH, it would make sense to make a limited job that isn't inherently related to the main content/game a pet class. This would allow the complicated -and potentially fun aspects- of the the pet class to be fully demonstrated for those who miss that aspect on the SCH/SMN, allow the job to be overpowered with stronger tamed creatures breaking the balance at the same level like BLU, and at the same time prevent such a 'difficult design/gameplay' from interfering with regular content (though I hope I'm wrong about managing pets being too difficult because some people do miss that aspect entirely as a 'pet' job in SCH and in regular content). If BST does become a thing, there's more likely a chance for it to become a limited job of collecting and taming creatures around the world (and I'll love that aspect; been waiting to tame some animals in Yanxia).

I just hope they add more content for limited jobs in particular - and not just in the collection sense but more of a dungeon sense & a roulette for events. That way people can play both BLU and BST together, bringing back some joy and making those jobs fun and not just a one-off thing where you collect and then have no content you can run together with. It'll make finding a party for the job less difficult as there are content to run BLU with.
