Astrologian is my new main, but it has some problems.
DPS is on the low side comparably to other healers, it seems. I could be wrong because I don't have a parser, but it really feels that way. I'll note that this isn't a huge problem overall. It's still plenty enough to solo, and adds an alright amount to party wide dps should it be needed.
Collective Unconscious - Why. Seriously, why? So, the 150 potency regen style isn't *awful* because it can stack with other things to be *alright* and nothing more. 50 potency more than the whm version for good reason. The 10% damage reduction that we have to channel? Absolute garbage. Sacred soil is already rarely used, and you give us a worse version of it? The only time this is EVER useful is during the phase change on certain bosses. Even then the effect is negligible, considering you can't be healing during this time.
Most of the cards feel good to use, by themselves. Royal road for extra potency or extra up time, whats to hate? but then we get to the 50% potency reduction and AoE...This is only really useful for 8 man parties, and only in extremely narrow circumstances. For example, Bole becomes a 5% damage reduction AoE, so that coupled with CU can be a 15% damage reduction. Which is cool for extremely choice rare mechanics and phase changes... Balance is super useful, because 5% on every party member is great! Spear and Arrow work similarly. AoE spire is only good if you lack mages, AoE Ewer is only useful if you lack Physical dpses. Both are better off being enhanced or used raw in a balanced party.
Celestial Opposition feels awful, but its not on global cooldown so, no cost free stun that increases the duration of my own buffs. Eh, There's no reason not to use it, so this skill gets a pass. I'd honestly prefer the stun part be removed and the ability get some other party utility, Maybe 10 second increase instead of 5? Buff spreading? I dunno, something.
Edit: To be clear, if I had it my way, the classes "utility support" abilities would be much stronger, and the actual healing of this class would be much lower, but that's just personal preference.
I'm open to feedback.
