On the one hand, it does feel like a glaring omission that some jobs got specific gear made for them while others don't. OTOH, it does seem niche at best especially considering the gear will be outgrown anyway.
That said it does seem like it is addressing several issues that might be better addressed separately, or are already accounted for.
I'm not against the idea of AF-lite sets for xpac jobs across the levels on principle, but I do think it might be a hard sell. And that the issue is more that the equivalents were supposed to be endgame gear and that xpac jobs start at a point where that level is no longer endgame. So while it makes sense to make i90/130/370/400 gear for xpac jobs, it also makes sens to...not do that.
- the Bias of certain Jobs in gear design: that could just be addressed by well, better gear design, we have sets that predate those jobs but still fit their aesthetics to a Tee. All the devs have to do here is to keep in mind that (for example) not every caster looks like a cultist or witch and not every tank is clad in armor form head to toe
- Model reuse/availability: As the post above said it might be better to make unlocked versions of said gear, but the problem is that it seems to be a very rare option, only the Sky Pirate, Sky Rat (despite being simialr looking to the point of redundancy) and most of the Shisui gear got that treatment so far.
- Lack of gear for that range: I mean, the MSQ should already give you gear, but that does seem more like a stopgap since its one use. OTOH if you did have 1 job capped, that means you do have the means to gear the rest as well, even if they're a different role. Also not helping is that bar BLU, they start at a later level and thus necessitate that you have another job and poetics access already at the point where you can unlock it. Even those starting at 30 have this quality due to a MSQ gate. The difference seems to be the amount of effort you have to exert for relevant gear, which seems to be another issue worth discussion.
That said I have to admit that unless the gear is dyeable or very uniquely colored like the i90 MNK gear then its gonna have a very niche place in my glamour wardrobe at best.
