It goes without saying that Discipline priests will use one of their
major glyph spots for the Power Word: Shield glyph as the spell is a
cornerstone of our build. And as Flash Heal triggers Grace,
Inspiration, Rapture and Renewed Hope, it's a safe bet for major glyph
spot number 2.
Based on the recommendations at Violaceous Mana, I took the Prayer of
Healing glyph as my third one. However, having read some discussions
over at Matticus's blog and on the PlusHeal.com forum, I wondered if
I'd chosen incorrectly. Some Disc Priests were recommending the Holy
Nova glyph instead, and so with a few hours left before I can escape
work, I thought I'd do some math to see if I should re-glyph.
(Warning: I suck at math. Hard. Core. Which makes theorycrafting probably pretty darn futile on my part.)
HOLY NOVA
Heals: At level 80, Holy Nova heals group members within 10 yards for
713-827. Holy Nova benefits from 30.35% of your spellpower, so with
1700 spellpower (Khæli's current level) and with the Twin Disciplines talent, it'll heal each nearby party member for roughly 1260-1410.
Mana Cost: Holy Nova costs 25% of base mana, which translates into 965 at level 80. With Mental Agility, this is reduced to around 870 mana.
+/-: It's instant cast, and therefore benefits from Twin Disciplines
and Mental Agility. It deals damage (398-462 base damage to all
enemies within ten yards). It does not trigger Inspiration. The ten
yard radius requires party members to be near me to benefit.
Glyphed: Healing is increased by 40%, while damage is decreased by
40%. This increases the heal to around 1047-1215 per group — around
1562-1730 at 1700 spellpower.
PRAYER OF HEALING
Heals: At level 80, Prayer of Healing heals group members within 30
yards for 2091-2209. This spell benefits from 80.68% of spellpower, so
with 1700 spellpower, it'll heal party members for roughly 3462-3580.
Mana Cost: Prayer of Healing costs a hefty 48% of base mana, which at level 80 is 1854.
+/-: 3 second cast time. This spell does trigger Inspiration. The
thirty yard radius allows for more distance between healer and tank
(and encounter).
Glyphed: Heals an additional 20% of original heal over six seconds.
At 1700 spellpower, this would add a HoT of 692-716 to the heal.
Total Amount Healed:
Glyphed Holy Nova: 1562-1730
Glyphed Prayer of Healing: 4154-4296
Heal Per Second (Total Heal Divided by Cast Time — or by 1.5 in the case of Holy Nova):
Glyphed Holy Nova: 1041-1153
Glyphed Prayer of Healing: 1384-1432
Heal Per Mana:
Glyphed Holy Nova: 1.82-1.98
Glyphed Prayer of Healing: 2.24-2.31
For group healing then, Glyphed Prayer of Healing wins on all accounts,
even (and somewhat surprisingly I guess since I've always considered it
to be such a mana-heavy spell) in terms of HPM. That it heals for
more, for less mana per heal, at a larger radius confirms Violaceous
Mana's assessment that PoH is the way to go for the third Disc glyph.
(It's not like I really doubted her in the first place, just for the
record.)
PoH is amazing on Loatheb. @.@ Glyphed PoH must be ridonculous!
Holy Nova might not proc Inspiration but it does proc Divine Aegis. I do find myself using nova a lot more now as disc for certain encounters. Thanks for linking to me!
I disagree with PoH glyph, I’ve used it in heroics and it’s great but once you upgrade out of the H’s… all you use PoH for is Loatheb and specific fights where you’ve arranged groups FOR PoH (which I’ll do for Malygos).
Aside from 2 specific fights (1 of which the +HoT doesn’t even work on) you’ll probably notice its percent of your heals as low, and overheal high.
Not that it’s that great but, with my Renew’s ticking for about 1 mil healing in a 10 clear of Naxx… the glyph can possibly cranked that number up… it’s something I need to try next clear.
