Source Disc Holy

Discipline LootRank

Holy LootRank

Pawn values

Pawn values for these are:

( Pawn: v1: "Discipline31": Stamina=0.2, Intellect=0.8915, Spirit=0.3223, RedSocket=12.5323, CritRating=0.3564, MetaSocket=18.7224, HasteRating=0.2925, BlueSocket=10.1323, YellowSocket=14.2647, SpellPower=0.6, Mp5=1)

( Pawn: v1: "Holy31": Stamina=0.2, Intellect=0.6890, Spirit=0.5222, RedSocket=10.9123, CritRating=0.3763, MetaSocket=14.4697, HasteRating=0.3059, BlueSocket=9.6897, YellowSocket=11.0246, SpellPower=0.6, Mp5=1)

Note that the gem values are derived from the best-in-slot blue gems for each socket. These for both specs are Insightful Earthsiege Diamond (meta), Brilliant Autumn’s Glow (yellow), Luminous Monarch Topaz (red), Dazzling Forest Emerald (Disc – blue) and Seer’s Forest Emerald (Holy – blue).


How much MP5 are abilities worth a T7.5 gearing level?

  • Replenishment about 180-200 MP5
  • Shadowfiend about 100-110 MP5
  • Rapture about 165 MP5
  • Holy Concentration about 50 MP5
  • Divine Aegis about 130 MP5 at 20% crit
  • Surge of light about 145 MP5 at 20% crit
  • Inspiration about 60 MP5 at 20% crit

Basic sensitivity analysis

The numbers don’t change much based on starting heroics and T7 gearing levels. As would be expected there is relatively less importance attached to Crit and Haste rating making spell power more valuable.

Starting heroics

(Spell power: 1200, IFSR MP5: 200, Spirit: 500, Int: 700, Crit: 12%)

Source Disc Holy
MP5 1.0000 1.0000
Spirit 0.2767 0.4705
Intellect 0.8465 0.6486
SP 0.6000 0.6000
Crit rating 0.3039 0.3462
Stamina 0.2000 0.2000
Haste rating 0.2413 0.2503

Starting T7

(Spell power: 1400, IFSR MP5: 230, Spirit: 600, Int: 800, Crit: 14%)

Source Disc Holy
MP5 1.0000 1.0000
Spirit 0.2958 0.4922
Intellect 0.8630 0.6646
SP 0.6000 0.6000
Crit rating 0.3179 0.3546
Stamina 0.2000 0.2000
Haste rating 0.2550 0.2657

T7.5 Raid buffed

Numbers for the original data with some raid buffs (Blessing of Kings, Mark of the Wild, Divine Spirit, Arcane Brilliance, Inner Fire) are pretty similar to unbuffed. You could throw even more buffs in there but the effect is minimal on the final gear list.

Source Disc Holy
MP5 1.0000 1.0000
Spirit 0.3836 0.6120
Intellect 0.9941 0.7826
SP 0.6000 0.6000
Crit rating 0.3686 0.3848
Stamina 0.2000 0.2000
Haste rating 0.3043 0.3216

Thanks for reading and your constructive comments.

Gobble gobble.

    Yes, my head is definitely hurting.

    It’s very interesting to loot at your Disc and Holy Lootranks side-by-side and see the similarity between the two. This is reassuring as I anticipate having to switch back-and-forth between Holy and Disc, and as such won’t find myself having to amass completely different gear sets (this is a testament, perhaps, to Ulduar itemization).

    Thanks for running the numbers, Bob.

    focused on the disc-values:

    Thanks for the work … but i feel a little uncomfortable with your values, cause the are based on mp5. so mp3 is rated very high, and it’s a mana-regen-stat.

    right now i have no issues with my manaregen, so i am wondering, why i should bother. if someone knows good values based on sp or HPS, please link (or mail me).

    @jedimax – The Doctor at Elitest Jerks has a set of “throughput” weightings which might be of use.

    Hey Bob—Malgayne from here. You may know that we use a Stat Weighting system similar to this on our site. (

    We have preset scales for different classes, and I wanted to update the scales we had to something that looks a lot like what you’ve come up with here. I’d love for you to contact me ( if you make changes or updates to these.

    Excellent work. 🙂

  17. Firebert says:

    If you don’t mind, I’ll post my weightings here for 3.2, based upon my char (assumptions below):

    MP5: 1
    SP: 0.6
    Sta: 0.2
    Spi: 0.2953
    Int: 0.8407
    Crit: 0.3563
    Haste: 0.2971

    MP5: 1
    SP: 0.6
    Sta: 0.2
    Spi: 0.4918
    Int: 0.6463
    Crit: 0.3956
    Haste: 0.3103

    Modified Assumptions:
    Time inside 5 second rule: 100%.
    Replenishment Uptime: 65%.
    Replenishment mana pool return per 5 sec: 0.2%.
    Shadowfiend hits 10 times and returns 5% of your mana pool every hit.
    Rapture procs every 15 secs.


  18. Firebert says:

    Erk, I wish for an edit button :/
    Just did some gem tables to make finding the best gem for each spec easier, and it’s come up with:

    Red: +9SP +8Int
    Yellow: +16Int
    Blue: +8Int +3mp5

    Red: +19SP
    Yellow: +9SP +8Int
    Blue: +9SP +8Spi

    with both metas as the Insightful Earthsiege (~80mp5).

    Spell power for Holy? I’ll mess with the gear and see what it does to itself, but I’m pretty sure I should be gemming differently.

  19. BobTurkey says:

    Those gems agree with what I use.

    I’ve steered away from +19SP gems previously as they were selling for 100+ gold a piece, but now their price iss tarting to come down i’ll start using them.

    You’ll probably find your stat weights prodice a gear list pretty much the same as mine.

  21. […] Previously for 3.1 I did a mass of work theorycrafting a set of stat weights for healing priests. This is the updated version for 3.2. To prevent having to post another six or seven post series explaining all the detail I am just going to post the summary (at this point). The formula are all the same with the exception of Replenishment, which has been simplified. For the detail of how these calculations were made refer to that older post. […]
