Thoughts:
OVERALL
First, I’m glad Blizz moved away from PI buff system for Oracle. Thank you, Blizzard. Of course, a few talents are still under construction, so feedback is limited. These talents mostly offer little throughput increases with a bit of extra manual interactivity from the player, which sounds about right for the scope of hero talents. I suppose my biggest concern here is that the Disc hero talents seem generally more impactful than the Holy ones.
PREMONITION
I appreciate that this talent adds some flexibility. It seems especially helpful in a raid setting where we can use it to redistribute overhealing. I remember the Velen’s trinket from Legion was extremely powerful for Disc in a raid setting because it redistributed so much atonement overhealing during burst windows.
I’m trying to figure out where we can use the 5s CD reduction. It would probably work best with spells that have a 15s CD or less. I think it could be useful if we wanted a quick application of three PW: Shields, like a mini-Rapture, since with enough haste it would reduce the CD of PW: Shield to around the global cooldown. It could also work well for using more SW: Deaths for Inescapable Torment. For Holy, I’m not really sure where I would use it except for maybe in raids to weave in more Prayers of Mending and Circles of Healing.
The 25% ST healing increase seems good for Disc in particular in arena, and in M+ during certain mechanics that target a single player with high sustained damage. Holy already has two Serenity charges and Guardian Spirit on a 1 min CD (effectively) to deal with that, but its ST healing in-between isn’t the best, so perhaps it could help in-between those other CDs.
Since Premonition seems to be aimed at getting in more use of short-CD spells, it seems necessary for Premonition to be off the GCD. Otherwise, it would probably jam up the rotation too much.
I appreciate the increase to atonement duration via Pre-Emptive Care. This is a great quality of life increase for M+/PVP and a great benefit for raids.
I really, really like Miraculous Recovery. It will make priests an excellent triage healer, especially when focused in PVP when it is difficult to hard-cast things.
I also appreciate the option for a lower-CD Purify. I’ve seen Priest class fantasy as being sort of the “dispel kings,” and the nerfs to Mass Dispel really got me down. So I’m glad to see more buffs in the dispel department.
Assured Safety seems ok. It’s a nice little throughput increase, I suppose. I guess it’s just…kinda boring? Still, a boring minor throughput increase is better than a frustrating talent. Gotta have some rice in the burrito, I guess?
Stronger absorbs and DR are always welcome, so I like Foreseen Circumstances and Preventive Measures. But like quite a few of the hero talents, the Disc version seems quite a bit stronger than the Holy version.
Perfect Vision (6 seconds off Premonition) seems a bit underwhelming in particular and not particularly useful. Maybe replace it.
I echo the other comment that it’s good that Grand Renewal grants another charge of Premonition, and I wish Answered Prayers was like this as well.
So generally, a good step forward, IMO. Interested in seeing the talents that are under construction.
