Pretty sure 1-3 have been scrapped; 1 is a neat idea that they probably didn't have any idea how to balance into normal parties and probably didn't leave an opening so they could code for it; 2 is a rather grandiose idea and also currently there's like NOTHING IN THE OPEN WORLD TO USE THEM FOR (lolhunts anyone?), in raids or whatever that would make things real weird; 3 yes machinist is pretty much going to be our musketeer because 2 gun jobs would be superfluous the same way that adding thief would be superfluous with ninja.


For 4, it's probably not a great use of resources to do, considering you're basically making an environment that lasts like 3 minutes but would need to pretty much make a complete small zone for a feature like NO ONE would use except RP'ers. FC airships flying around would be pretty dope, I was pretty disappointed with the glorified retainers we got. If anything it could be a mini game part of the Diadem revamp hopefully, but I kinda doubt they'd casually let us fly it around the open world.

TL;DR: SE started out with some more grandiose, neat ideas then both underestimated how they could allocate resources to them, and also how to fit them into their very codified, set in stone MMO.
