My recommendation of Tsanga's as the offset was for normal. For heroic, your best offset is probably chest>shoulders>hands. (Of course, I don't think many people are in a position where they have access to all heroic gear at this point.)

I'm curious about whether Mew is modeling based on the 4.0.6 changes to bleed damage. If it's not, then the DPS increase will actually be higher, since the relative value of mastery will drop slightly.

For those that were curious, I did put together a new equation for a static comparison on the new Unheeded Warning (increase weapon damage by 680 for 10 sec).

321 * <value_of_agility> + 680 * <value_of_weapon_dps> * 10 / (50+8)

You'll have to grab your own RSV values to get a good number, but for me (in pre-heroic gear), it's looking like Unheeded Warning is actually BiS, followed by Fluid Death, then the heroic raid trinkets. I suspect that is likely to change by the time my gear is good enough to actually be considering those choices, though, so take this with a grain of salt.

I should also point out that using this during a Berserk-Shred spam could produce massive numbers, and I'd like to see sim scripts to know if that is actually enough to delay using Berserk.



On a slightly different note, I didn't offer up the equation for damage proc trinkets before, so I'll add that here.

Darkmoon Card: Hurricane - 321 Agility, Equip: Chance to strike your enemies for 3750 to 6250 nature damage when dealing damage with melee or ranged attacks. (1 ppm)

This actually deals with two interesting parts of the equation: damage proc and proc-per-minute items

I'm not certain that this is the best way to model a damage proc, but it seems to work out pretty well for me. I've tried to model it as an increase to the damage of 1 attack by an equivalent boost to AP for 1 second.

<average_damage> * <value_of_AP> * (convert AP to DPS) * <white_damage_%> / <time_to_proc>

To convert AP to DPS, multiply by 14, then divide by 1.25 because of our boost to AP in cat form.
To find average damage, just add the min and max, then divide by 2.
Get your white damage % from a recent log parse or damage meter.

Which leads to the following equation:
(3750+6250)/2 * <value_of_AP> * (14/1.25) * 0.15 / <time_to_proc>


Now, moving on to the second part, how to find the time to proc on a proc-per-minute item. It sounds simple, right? 1 ppm means 60 seconds to proc? That's true, but only if you have 0 haste and do nothing but auto-attack. Proc-per-minute items are actually converted to proc % based on your character's weapon speed. Cats have a 1 second swing timer, so this becomes a 1/60=1.67% proc chance. This can proc from any direct attack, which includes white attacks, shred, mangle, rake (initial), etc. It will not proc from bleed ticks. I haven't seen any data to show that there is any cooldown on this type of item.

So the time to proc can actually be determined by looking at how long it will take you perform 60 attacks. Haste can be a factor here, but I'm going to ignore that for simplicity. For my calculations, I assume that we perform a white attack every second and a yellow attack every 4 seconds on average. This means that our average time to proc will be about 48 seconds. I'll subtract 2 seconds to account for haste, since I've got a miniscule amount of it.

(3750+6250)/2 * <value_of_AP> * (14/1.25) * 0.15 / 46
182.61 * <value_of_AP>

Substitute in your AP stat value and you've got it.

In my pre-heroic gear, it puts the Darkmoon Card: Hurricane right in the middle of the pack for the 359 trinkets.

*Edit*
I want to point out that an accurate simulation is ALWAYS going to give more accurate results than this type of formula.

The purpose of doing this type of calculation is to get an understanding of trinkets that are: not modeled, modeled incorrectly, or sanity checks for simulation. The main reason I use it, though, is to put together a list of ranked item upgrades without requiring extensive use of simulations. (Run it once to get RSV from my current gear and plug that into the spreadsheet.)

Assuming Rip is calculated as given in the thread by
57 + 144 * nrCPs + AP * 0.023 * nrCPs (Per tick)
and that Rake is calculated as given by
555 + 0.14 * AP (Per tick)
and further assuming a very conservative raid AP of 15750 AP I've calculated the following numbers:

Dps of assumed AP Rip (With Mangle):

• Rip 0x SotP - 2,937.48 dps
• Rip 1x SotP - 2,958.77 dps
• Rip 2x SotP - 2,980.07 dps
• Rip 3x SotP - 3,001.36 dps

Dps of assumed AP Rake (With Mangle):

• Rake 0x SotP - 1,196.00 dps
• Rake 1x SotP - 1,205.56 dps
• Rake 2x SotP - 1,215.11 dps
• Rake 3x SotP - 1,224.67 dps

If I'm reading your question right, you're wondering if, assuming Ripping will let SotP buff fall off,
is it better to Mangle to refresh SotP and then Rip.

Assuming you rip and then build up SotP over the next 60 seconds via 3 mangles:
You would have 30 seconds of SotP x 1 and 30 seconds of SotP x 2 before reaching 3x SotP again.

I'm assuming rake will not also immediately fall off. Additionally, to make the calculation nicer, I'm going to assume you have 6 seconds of 3x SotP rake before you have to refresh. You would then have 6 seconds of 3x SotP rake, 30 seconds of 1x SotP Rake, 30 seconds of 2xSotP Rake before reaching 3x SotP with Rake again.


Assuming you Mangle first, then Rip:
66 seconds of 3x SotP Rip ~= 198,089.76 damage
66 seconds of 3x SotP Rake ~= 80,828.22 damage
Less: 1s rip up-time penalty = -3001.36 damage

Total Damage: 275,916.62

vs.

22s of 3x SotP Rip ~= 66,029.92 damage
22s of 1x SotP Rip ~= 65,092.94 damage
22s of 2x SotP Rip ~= 65,561.54 damage
06s of 3x SotP Rake ~= 7,348.02 damage
30s of 1x SotP Rake ~= 36,166.80 damage
30s of 2x SotP Rake ~= 79,946.12 damage

Total damage: 276,630.52


Thus the damage loss at assumed stats for refreshing SotP before Rip: 713.9 (~0.258%)

Realistically this number would be a slightly larger dps loss as Mangle, Ravage, and Shred are all marginally effected by SotP and I have not factored that in.

So you're losing a bit more than a quarter of 1 percent of your dps for the next minute by refreshing SotP before Rip. If you were averaging about 17,500 dps, the dps loss you would incur I would come out to be ~45 dps plus the loss from Shred, Mangle, and Ravage. So assuming a harsh overall 55 dps loss and you're looking at losing 3,300 damage over the course of a minute. While very marginal, it's still technically a dps loss.

Refreshing Rake over SotP is a different story. Using the same method as above, I'm showing refreshing SotP at the cost of 1 second of Rake up-time is actually a dps gain of ~1,795.97 damage over 75 seconds or a ~23.94 dps gain which works out to be around a 0.14% dps increase. This would be slightly mitigated by the loss to Mangle, Shred, and Ravage dps that I have not calculated but assuming roughly the same loss as above it would still be an *extremely* marginal dps gain.

So in general, based on this napkin math, you'd put refreshing SoTP on your priority list below refreshing Rip but above refreshing Rake.

Edit: Toying around with Simcraft tells me that, in BiS 372 gear, refreshing Rip over SotP is roughly a 46 dps loss (~0.22%) and refreshing both Rip and Rake first is a 52 dps loss (~0.25%). This indicates that it is a slight dps gain to refresh SotP before Rake and Rip. It appears that, with other buffs factored in, it becomes marginally better to refresh SotP over rip as well as rake.

Jazdia&Leafkiller: So, while you didn't state this directly (or I overlooked it) I assume that stacking up SotP at the beginning of the fight is a priority as well.
Experimented a bit during (way too) many Nef attempts yesterday, and found that it felt the best to simply substitute the first Shreds with Mangles, This way, the first Rip already gets two stacks of SotP, or even three in the case of no crits. Of course, Math might disagree.
