Astrologian impossible to balance as it is

[NamoNanamo]

It wouldn't be too overpowered in my own opinion, but it wouldn't serve too much incentive to do so either. There would be no reason to Sect Swap when party with a SCH since you don't want to risk overriding Deployed Adlo / Crit Adlo. Double hot + a shield would have some applicable use in WHM/AST compositions and probably make it a bit more desirable but it's hard to fill the niche that SCH currently has in the current meta iteration so this composition will be unlikely to oc

I mostly agree.

WIth a whm, you could diurnal in stance dps+ hots; and switch back healer stance with nocturnal for shield and stronger heal. It would lead to a better mp management.
You could do the same with sch but it would be less efficient and you'll need to coordinate with your scholar.

At least, it would be fun cause since Monday, I'm playing noct Astro on a3s with a whm and I'm sad to not get the 5%as while I'm dpsing.
