I'm not sure where l heard this from, or if l even heard it correctly, and of course I would take it with a grain of salt. That being said, I think, since the dev team is ahead of schedule on the expansion and has a larger budget this time around, might add another job sometime after Stormblood's initial launch like they did with ninja. It's obviously not confirmed in the slightest if I even heard the statement correctly from whatever interview translation l was watching at the time. If they do though, maybe they'll even think about adding two jobs. One healer and one tank. It's not the best situation but It'd be better than waiting two plus years for more tank and healer jobs. Just my filthy-casual two cents on the matter. I do hope that tanks and healers get some love with new and existing jobs during Stormblood's life cycle though.
