Stat weights/Best stats for Astrologian?

I apologize in advance if I posted this in the wrong section.

Anyway, we are 2,5 months into Stormblood, and I still haven't been able to find any lists with the best stats to go for on my healer (I main Nocturnal AST in Savage mode).

Would anyone have an idea what I should meld? I was thinking of CRIT/DET and SpS when either Crit or Det is not doable (which is what I have been doing) myself, since I figured SpS doesn't do a lot for my shields, plus I don't feel that SpS makes a huge difference castwise. But I may be wrong. Or maybe I should go for a different route entirely, and meld PIE or perhaps VIT for survivability?

Are there any Nocturnal ASTs out there that could shed me some light or give me their opinions? All help would be appreciated :)

Do you limit yourself to just Noct?
Wether you go Diurnal or Nocturnal should depend on your other healer. Diurnal with Scholars and Nocturnal with White Mages.

I'm in a static with a WHM, so I'm basically a "permanent" Noct AST.

So far, I've been slapping as much crit on my equips as possible, and then defaulting to DET when not possible. SpS is a nice bonus, but I don't think it gives any serious advantages for Noct sect.

You'll want to meld Vit in particular for O4S progression, to get yourself above 35k health (with food). That should only take a few Vit melds, but I've done the whole right side while we work on Exdeath.

For shields go Det/Crit

For Regens go Crit/SpS

For astro you just wanna try to balance the three as best as possible as leaning into too much SpS hinders your shields while leaning too much into Det it hinders your regens. Det does contribute to regens, but crit and SpS scale much better for those.
