So do we have somewhat of a consensus on how to weight each value in terms of dps increase? It looks like it's shaping out to be something like this at around 3000 AP.

AGI = 2.5
STR = 2.4
AP = 1
CR = 0.8
Haste = 0.7
Hit = 0.7

That doesn't look to be factoring in Blessing of Kings and the 3% to all stats talent.

Assuming the above.
STR would then be 2.72 (2.4 * 1.1 * 1.03)
AGI 2.83 (2.5 * 1.1 * 1.03)

Given two items of nearly the same dps from the above, I'll favor one with hit versus one without hit (until close to the cap).

Its not always about losing /gaining dps, its about personal preference choices when the dps difference is minor.

Of course it depends if you have kings or not, and in most situations where it matters you will. Bufferd only with kings and my own MOTW i have around 3000AP.

AGI = 2.88
STR = 2.70
AP = 1.00
CR = 1.77
Haste = ??? (I still don't model this yet)
Hit = 1.26
Weapon = 12.33 (for things like the Crystalforged Trinket and ring enchants)

Very well put. The predictability effect is hard to quantify but it's definitely there.

I don't want to factor in kings. Why isn't weapon damage rated at 14 out of curiosity, because it doesn't add rip damage? Does the natural weapons bonus apply before or after +damage bonuses? Sadly I don't have a crystalforged myself to look at a paperdoll.

Does anyone know how the Everbloom Idol and Nordrassil 4pc Bonus work? Are they applied before or after Mangle?

As far as I know it's been decided already that yellow attacks are indeed on a two roll system whereas white attacks are on a single roll system. There's several threads on this forum with evidence to back this up.

Having monitored the WWS for myself and another feral druid over several weeks of raiding now, I can attest that crit % is consistently lower for yellow attacks than for white attacks when equipped with less than 8.6% hit, and the difference becomes notably more apparent with lower levels of +hit. To me this is a pretty clear indication of a two roll system on yellow attacks, and personally I'm satisfied that this is indeed how it works.

With this in mind, +hit (and FCR) becomes significantly more favorable, as Crit % on specials (CS%) becomes (Crit % x (100 - Miss %)).

So for example,
at 0% Hit and X% Crit, CS% = 0.914X
and at 1% Hit, CS% = 0.924X

With say 40% crit that's an increase of 0.4% CS per +1% hit which provides a fairly significant increase in dps, all things considered.

Thanks a lot for this, I'll update to take this into account.

This part I'm not convinced by. Roughly speaking, I've assumed that if you miss a yellow attack then you wait 0.7 seconds (for a 40 energy attack) and try again, and thus get another shot at critting.
However there will be an increase to the worth of +hit, because a single-roll system with refunds on misses inflates your effective crit rate when you miss a lot. Extreme example: 50% crit, 50% miss, on average it takes you 2 attempts to land an attack, so the energy cost is 118% of normal and your effective crit rate is 100%. Adding +hit will reduce your DPS. This effect is represented in my model by reducing the energy cost of attacks by a proportion of your miss rate, while leaving crit damage unchanged.
EDIT: better way of saying this - in a single roll system with refunds, your attacks cost less energy on average, if you miss a lot. Since crit rate is unaffected by miss rate, and energy cost goes down with more misses, DPE of crits goes up and so crit rating is overvalued.
It's possible this is just another way of looking at the same thing, I haven't had my coffee yet

Solstice, this doesn't make hit significantly more useful at all. It does make it slightly better, though, but still it has no effect on the primary idea that a missed special costs little energy. Granted it's slightly better than it would be with a 1-roll system, but far from significantly more useful.

Heh, well it depends what you deem to be "significant". I'd argue that an extra 0.4% crit on specials (non-finishers) per 1% hit is more than "slightly" better than none. I agree that it's not effecting the point in question but nevertheless it's a fairly notable factor when determining how much weight to put on +hit, at least for me.

Hmm, interesting. So wait, let me check I'm understanding this correctly.

In a single roll system, increasing +hit actually reduces your effective crit, because if you score a hit rather than a miss then you can't then use 82% of the same "lump" of energy to try and land a crit. So DPE of crits effectively increases as you reduce your chance to hit.

Inversely, in a two roll system increasing +hit increases your effective crit because you can't crit if you can't hit - there's a roll for hit/miss/dodge (block/parry) and on hit there's another roll for crit/non-crit. Therefore you can't "re-use" the energy recouped from a miss in order to crit as miss and crit aren't on the same table.

This seems to provide some logical explanation as to why Blizz chose to implement a 2 roll system for specials.

While it's interesting to try and model the relative value of +hit compared to other stats, I think there's limited value in the results as there are simply too many permutations. Some of them have already been mentioned, such as clearcast procs, missed finishers, missed mangles causing reduced rip ticks, etc. These are possible (although probably not easy) to model. But then there's the human element, which will vary from player to player and is not something that you can really quantify. For example things like missing a mangle then shredding without the debuff up, or missing a shred when on 4cp and ripping before you notice, or missing a special at 50+ energy and powershifting.

So while I don't doubt your figures I don't think that you can look at them and deduce that say, "1 strength = 0.7 hit" in terms of raw dps - while this might be true in theory, in practice there are other factors involved that can't be modeled which make +hit more valuable. My gut feeling is that, point for point, +hit is the most valuable dps stat right up to 8.6%.

World of Warcraft doesn't run on a Gut based calculation system. If you disagree with the math and think there are things that it's not modeling then by all means question that. However to look at such a giant disparity with accurate math behind it and disagree with it fully seems a bit silly. There are human issues for sure but I can't imagine that making up for a 30% difference.

Melee crits deal double damage.
