I hope they add Primal versions of weapons for the new classes.
I doubt it. Why would they go back and make a new questline for Zodiac with 1 weapon. Also we dont know the limitations on the job requirements. Whether Stormblood is required or not, whether you need to be a certain level or not, etc.
