So I logged on the PTR.
Healing stats comparison:
10% healing buff comparison on current character w/ 27% crit, 10% haste, 43% mastery, 8% versatility…
FC5 stack Heal
PTR: 8,425
Live: 7,626
Flash Heal
PTR: 5,041
Live: 4,563
Prayer of Healing
PTR: 2,173 per target (x5) = 10,865
Live: 1,967 per target (x5) = 9,835
Mana cost: 2,500 baseline
Mana cost w/ Prayer Circle: 1,875
HPS w/ Prayer Circle (1.4s cast vs 1.8s): 7,760 hps
HPM w/ Prayer Circle: 5.79
vs FC5 heal
HPS: 5,616 hps
HPM: 7 hpm
TLDR: Buffed Prayer of Circle PoH will do 38% more HPS than Flash Concentration heal, but will cost 17% more mana to use. This makes Prayer of Healing + Harmonious and spamming Prayer of Healing potentially competitive against Flash Concentration if you do not use Resonant Words.
Damage Abilities
Divine Star
PTR: 1,727 (per target)
Live: 1,573 (per target)
Chastise
PTR: 4,317
Live: 3,011
The damage bonus also applies to Boon of the Ascended. Holy Priest w/ Kyrian Legendary will be able to do 5.5-6.5k dps in keys easily making us one of the highest dps healers in keys outside of Resto Shamans since Holy Paladins got a pretty big nerf for Venthyr.
Talent Changes
Binding Heals (new talent) now takes the spot of Cosmic Ripple and is an extremely powerful talent. It stacks with Trail of Light so you can heal yourself for 55% of your heal & flash heal on-to other targets. In raids it’ll be a passive HPS increase (like having 10% extra leech) if you’re single target healing. It’s a much better option than what Cosmic Ripple was before so consider it a buff.
Cosmic Ripple got moved down to the same row as Surge of Light + Prayer of Circle and will absolutely not be picked over either of them.
The Afterlife talent is interesting if you can cast resurrection while in combat. This opens up the potential of Holy Priests killing themselves in raids so they can resurrect somebody and then get battle ressed after. I don’t really see any use for it outside of scenarios if the holy priest dies by accident in a raid or if you’re trying to resurrect people in arenas.
Symbol of Hope changes
This is more of an opinion piece, but I’m somewhat mixed on this change.
The cd being reduced to 3 minutes instead of 5 minutes now fixes the problem where you basically just sat on the ability until the healers were OOM at the end of the fight. Now the most realistic way to use would be to use Symbol of Hope after every single Divine Hymn or timed in the manner that you can use it 2-3 times in a fight (based on duration).
Overall mana gains will be doubled from what the ability normally gives if used 3 times on a fight vs 1.
I personally rather see it provide a damage reduction bonus instead of reducing peoples CDs. -20% DR for 8s (2s per channel) would be solid and get us into the meta tier.
Tier set bonus
There’s datamined changes on the Holy Priest set, but it’s not changed on the PTR yet.
Final thoughts
I plan on dumping my final thoughts on the PTR section, but overall the buffs are fairly solid. It doesn’t address some areas like Mastery not providing a damage increase (raid priest stack mastery) which will still put us on the bottom when it comes to raid damage output. On the opposite spectrum in M+ our damage is going to be absolutely S tier.
The Prayer Circle talent change for Prayer of Healing may potentially be a viable healing choice to play as Holy in 9.2 for raid healing and if you go that playstyle you won’t need the Flash Concentration legendary.
