[1.2.170] Elemental Pirates? New pet!

Warriors and magicians have three branches and now pirates are getting another one (if it is another one). Does this mean that maybe thieves and archers might get a third branch?

The most effective choices, I'd say, for 3rd branch jobs in that area, are the two existing Pirate classes. Gunners for Archers and Fisters as Thieves.

But yeah, this doesn't really seem necessary as a job on its own. I'm going to hope they're supplemental job specific skills that can be learned outside the system of the normal skill system, sort of like the common skills. I really don't want to see such an unneeded additional subclass to the Pirate class.

Are these things released then in kMSt? Have they mentioned them or explained them?
