@Naoki Yoshida-> Make Samurai a Tank class!

(If we got Viking I'd prefer it to dual-wield axes tbh)

Why? Did you have a better suggestion for a job to use Hammers/Maces? Because I can't say I know of any known for using them. Kind of seems like a waste to opt for dual wielding hand axes on a tank, doesn't it? When we have perfectly good shield models only being used by one job (with only a small handful actually being truly specific to Paladin)?

Healers are a whole other issue though, as they are practically even more stressed for viable job options than tanks in my opinion.

Pretty much. Which is why unfortunately we're more likely to get Red Mage as a Healer than we are to get them as a proper caster (with some manner of close quarters fighter being about equally likely as getting them as a Healer). After that? Kind of a weirder spot, and all you can really do is take a vaguely magically oriented job from someplace in the series' history and kinda convert it into being a healer (Astrologian being Literally Time Mage meets Oracle borrowing the name from Astrologer). I'd actually be inclined to say Bard would have been an excellent choice had they not kinda blown their load on that in 1.x assigning it to the Archer that was a shoe-in for becoming Ranger. Bishop barely qualifies as recurring and is sort of unremarkable unless you look at Bravely Second's take on it. In short, it's a mess, and as much as I wouldn't want it, they might have to opt for Red Mage in the healer role and bite the bullet and do some manner of Chemist later down the line. But oh well, there's always Green Mage, which is largely a blank slate outside of a small number of buffs in the Green Magic kit not being simple stuff other jobs have used time and again (Bubble and Oil come to mind).

I doubt they'd try and justify using Sage, but it's also an option.
