Original Post:

TLDR:

+1 INT = 3.5 HEP
+1 MP5 = 2 HEP
+1 Spell Power = +1 HEP
+1 Crit Rating = 0.5 HEP
+1 Haste Rating = 0 HEP

The Long Version:

I have played a priest and druid in raiding content, and am now gearing up my shaman for healing with the advent of 3.1 and dual speccing.

A very successful approach I used for the other two classes was to focus in my Oh Sh1t spell and figure out what combination of stats would return the largest TOTAL healing before I go OOM.

This approach has a very practical application for dungeon and raid progression, because when things go bad, as they frequently do, a wipe is usually saved by being able to cast a fast heal for a very long time.

By gearing to this worst case scenario, I found, anecdotally to be sure, that when things are going smoothly, healing is easy and trivial.

Please be warned: I am not saying this is the "best" approach. YMMV depending on the specific needs of your guild and the challenges of specific boss fights you may be stuck on.

I AM saying that this has been very effective for me to quantify gearing decisions for PvE progression content through end-game raiding.

1. Compute the Healing per Second of the spell you want to optimize. For LHW, a "simple" estimate:

hps = (1.0 + (cr/4591.0 + itl/16700.0)/2)*(1738 + 0.808*hp)*(1.0 + hr/3300.0)/1.5

cr = crit rating
itl = intellect
hp = healing power
hr = haste rating

2. Compute your mana consumption rate while spamming the spell:

mps = (645*(1.0 + hr/3300.0)/1.5) - (mp5/5.0)

3. COmpute the time to go OOM at that consumption rate

tOOM = m/mps

m = total mana at the start

4. Total Healing to OOM is:

hOOM = hps * tOOM

The following vb script computes the effect of adding various stats to the total healing output, normalized for spell power = 1.

You can easily modify it for other spells. It might be nice to extend it to include various talent effects, like mana tide, tidal force and improved ws procs. I will leave it to some ambitious reader as an exercise.
