Not always on cooldown - you should use PoM once your previous PoM has used up all of its charges. Refreshing PoM while there are still charges left is not usually a good idea, although you might do it in preparation for raid damage. When possible you should try to use PoM while borrowed time is active.
I recognize you never said "never use PoM" - I don't think that's the argument at all. I strongly disagree with your statement that it is not a good heal to use during heavy raid damage.
Regardless of HPS, you're going to get more healing out of PoH/SS than PoM with more Haste.
At base, PoM costs you 1.5 seconds to cast, PoH costs you 2.5. No matter how much haste you have (unless you manage to run into the gcd hard cap at 1.0 seconds), the ratio of cast time of PoM to cast time of PoH or 3:5, 0.6, or however you want to put it will remain constant.
For example: Let's say you have 20% haste.
Cast time of PoM (and your gcd) is now 1.5/(1+0.2) = 1.25
Cast time of PoH is now 2.5/(1+0.2) = 2.0833333...
1.25 / 2.0833333 = 0.6
PoM and PoH scale equally with haste. This is true in the general case as well - the presence of a haste buff does not change the relative strength of two spells; the exception being abilities that gain an additional tick when passing a haste breakpoint or having sufficient haste to push the gcd to 1.0 causing one spell to start "wasting" additional haste.
You're going to get more healing out of PoH/SS than PoM with more Mastery.
If I was to gain 30000 mastery rating (not a typo, I really do mean thirty thousand), 5 target PoH would almost catch up to PoM's hps. I think I'm safe for now. Spirit shell, of course, catches up much faster (breakeven is gaining a little over 3000 mastery). These numbers both assume I gained zero crit rating. I often do not refresh PoM until I have finished spamming spirit shell PoH's to preshield the raid (there isn't likely to be enough damage going out to make PoM bounce anyways) as I want to get in the maximum number of shelled PoH's.
Crit is unreliable, unless it's baked into the equation as it is with Spirit Shell. I've seen wild disparities between PoM and PoH crit amounts.
We're not talking about gemming or reforging crit here, just the unavoidable presence of crit from intellect, raid buffs, and whatever you happen to have on your gear. Also, crit mendings are less likely to overheal than crit PoH's because PoM is likely to be on a low health target.
I should probably have said in my last post that the non-crit scaling of PoM and PoH with respect to intellect is the same, as it is the influence of crits that causes PoM to pull ahead as more intellect is added and not some inherent value of the added int itself. This is relevant to the next section.
According to Nysem's math, PoM's spellpower coefficient for individual hits is 71.4% and PoH is 94.5%. Multiply by 6 and 5 respectively, and PoH ends up having the higher by "approximately 45% (additively)".
This is not how spellpower scaling works.
Pretend you have zero spellpower, no secondaries, and no buffs at all.
Your PoM would heal for 5919*1.25*6 = 44394 and your PoH would heal for 6957*1.25*1.6*5 = 69570.
44394 / 69570 = ~0.638
Alternately, PoM's hps is 44394/1.5 = 29596.
PoH's hps is 69570/2.5 = 27828.
29596 / 27828 = ~1.064.
Now with 10000 spellpower (same other conditions).
PoM now heals for (5919+0.571*10000)*1.25*6 = 87217.5.
PoH now heals for (6957+0.671*10000)*1.25*1.6*5 = 136670
87217.5 / 136670 = ~0.638
PoM's hps is now 87217.5/1.5 = 58145.
PoH's hps is now 136670/2.5 = 54668.
58145 / 54668 = ~1.064.
The ratio between non-crit PoM and PoH does not change as you add spellpower. They scale at the same rate.
You can repeat the calculation for any amount of mastery and show that mastery does not affect this scaling - it will however cause PoH to be closer to PoM (regardless of spellpower) and even pass it with sufficient mastery rating. Once you add in crit though, PoH once again falls behind.
Then you consider that you're getting more Mastery (12.5%) from raid buffs than either Crit (5%) or Haste (5%).
You also get crit from intellect and crit rating. Even if you have no crit rating on your gear you are still going to have about 10% crit raid buffed depending on your intellect. 1% crit is also a much larger gain than 1% mastery. Do your calculations over accounting for 10% crit (or more) and you'll see what I mean.
Then you have to think about effects like Inner Focus. Does your spread sheet take that into account? What about AA?
Inner focus does not affect these calculations in any way. You can still use inner focus on cooldown - your PoM is replacing one of the "other" PoH's you would have cast. More precisely (ignoring borrowed time which skews it in PoM's favor) you are losing 3 PoH casts and gaining 5 PoM casts (3x2.5 seconds = 7.5 seconds of casting time, or 5x1.5 seconds = 7.5 seconds of casting time).
This suggests to me another way to illustrate that PoM is better hps than PoH. Take your total average healing from one PoM cast (everything included, raid buffs, crits, all secondaries etc) and multiply it by 5. Take your total average healing for one PoH cast and multiply it by 3. That's the tradeoff (again assuming you never BT haste PoM which isn't a very good practical assumption since you should definitely be trying to do this but it makes things simpler).
Archangel affects both abilities equally so does not affect their relative hps.
@ guy above me: It is possible for people to post about theorycraft without hating each other, the game, themselves, and everything else. The priest forum is generally a pretty friendly place.
