So, I've got a theory atm about how to use Diurnal and Nocturnal sect, and I'm hoping y'all can help me out.
Since the AST is a healer support job, I was wondering if the intent behind the two sects was for us to "mimic" whatever healer the AST is paired with, allowing the AST to take some of the burden off of the other healer so that they're not racing to spam all of their healing spells and abilities to get the party up to full.
We already know that the AST lacks the healing throughput of the other two healers, but this mainly comes up because we have an AST attempting to replace a WHM when paired with a SCH, and vice versa. But when we do this, I think what this is doing is actually hurting the party makeup, because the AST already doesn't have the healing power of the WHM yet we're attempting to shoehorn them into that role because we don't want their sub-standard shields to get in the way of the SCH. I think that the AST should be using whichever sect matches the other healer, so that way you have multiple regens overlapping as if you had two WHM, or a mechanic is about to come up, the SCH can shield initially, and then the AST can follow-up after the shields are down, and mitigate more damage without the SCH wasting too much MP.
Again, I'm posting this because I need some help figuring out how well this works. I've been pretty busy over the last week, and having other healers help me test this is probably the best way to get feedback.
