I'm not able to sustain 22k+ dps over 5 minutes on the >80% target dummy solo and self-buffed, so if you're able to do that, it'll be worth my while to study your log.

My average values seem to be very close to yours, however your doing about 2k dps more and your pet is doing 200dps more.
Would you mind sharing the rotation you used?

I´m opening with my CDS, followed by 2 AiS. SS to regain focus and again AiS. I´m not using neither SrS/CS during RF, only SS+AiS. after that, the "standard" rotation. AiS whenever its possible, and CS to Refresh SrS. What I try to do is to force the MMM bug, I do SS in pairs, and after reaching 3 MMM stacks, I do SS until the fourth stack. When I reach it, I shoot one more SS followed by an AiS. That way you have always a 60% chance to retain the 50 focus cost. Glyphs are RF, SS, and AiS

My pet has 2/2 WH. Also I´ve removed as much mastery as I could, reforging it all to crit or haste if the piece already had crit. I am at 11.3% haste (1150 rating).

Anyway, I wouldn´t give too much credit to those numbers, as said, they´re are very anecdotal and Boss fights may differ a lot.

I'm curious about Pathing here. I'm only able to drop my Haste to a rating of 523, which puts me well over 4.4% with 3/3 Pathing. Since I'm 2/3 OwN and 2/3 Frenzy, would it make sense to drop points in Pathing and fill out those talents to get closer to the 4.4% Haste? I'm not sure what values Haste is going to have after that 4.4%, thoughts?

EDIT: Even femaledwarf shows a DPS increase with those changes (and my gear). It makes sense, but is a little surprising given how it has been treating Haste lately.
EDIT2: Going to 0/3 Pathing and leaving 1 piece of gear not reforged puts me at 4.5% Haste, but I'm left with nowhere to put 1 talent point. FD also shows this as a DPS loss (I put 1 point in Imp. SrS), but with 1/3 Pathing it was also showing Haste at 6 DPS per point, which I can only chalk up to FD being FD.

I believe dropping haste in favor of mastery in order to reach one of the theoretical rotation breakpoints is a bad idea for real world dps for 2 reasons:

1) In an Aimed Shot rotation mastery has simmed as 30-40% worse than haste at every gear level I've tested (from my own gear at ~350 ilvl up to 372 BiS). While the Wild Quiver proc chance did get buffed by 17% in the patch the switch to an Aimed Shot rotation has significantly decreased the number of chances for procs. For each hardcasted Aimed Shot cast we lose ~2 chances to proc wild quiver (~1 autoshot and ~1 arcane shot since AS is half the focus of AiS). In a 10s rotation using Chimera Shot on CD with one hardcast aimed shot and 6 other shots (either 5 steady/1 Fire! AiS or 6 steady) we have ~11 chances to proc WQ (sims suggest ~3.3s between auto shots when hardcasting AiS) whereas in a 10s rotation with Arcane Shot we would have ~13 chances a ~15% difference which pretty neatly counteracts the mastery buff.

2) Including latency and the inability to queue an ability after an instant until the GCD is finished the exact haste sweet spots to get an additional shot in will vary both from person to person and for an individual over time as their latency varies. To confirm this suspicion I took the BiS gearset from Simcraft and used the plotting function to show DPS as a function of haste (the gearset has 1425 haste on gear so the -1400 haste point is at 25 haste):

As you can see, there aren't any noticeable haste plateaus or significant changes in slope.

Based on this I would say for Aimed Shot rotations it's best to gear for haste over mastery. As gear levels increase haste also seems to approach crit in value, but I've yet to see a gear set where it is better by a large enough margin to consider prioritizing haste over crit.

Is there a way to calculate the dps gain you obtain from not using Cobra Shot for the first 3 rotation cycles of the Non-CS Rotation? I think that dps difference would be enough to bridge the gap between the two.

It looks like this.

Serpent sting, AiS, SS x2, AiS x2, SS x2, AiS, then the first cobra shot to refresh the serpent sting.

I can appreciate that, but I was only talking about dropping points in Pathing (to finish Frenzy and OwN) based on the 4.4% Haste needed for the rotation/priority that White has proposed. It's my understanding that the simcraft results don't actually model a proper rotation, so the numbers when it comes to Haste would be misleading as they aren't based on a proper priority/rotation. My knowledge of simcraft is abysmal, so feel free to correct me on that. It would appear though that Haste no longer drops in value once reaching one of these rotation points as it did with SV, for example. Which means our reforging would be more Crit > Haste > Mastery than Mastery > Haste.

Even so, dropping those points in Pathing in favor of the BM tree showed as a DPS increase even on FD, and while still having enough Haste to cover one of these theoretical rotations, I can only assume it's accurate.

Using my gear, I get very similar damage output as you, and serpent sting doing 11847 damage over 15 seconds, or around 790 dps.

If you replace the CS portion of your rotation with AI, then your total DPS for that rotation comes to
3 x 85835 + 6 x 15023 / 10 = 34764. The MMM procs will be the same 4935 for a total of 39699, a gain of 4173 dps. You lose all 790 of your SS dps though, so the actual difference is ~3400 DPS by just using AI and SS. You gain a GCD in the CA phase by not casting Serpent Sting, but lose a GCD after the CA phase when you will eventually want to cast it (but the GCD in CA phase is more valueable).

This might sound dumb, but why spec into rapid killing for raids?

I use 1 point due to add fights and the fact that there really isn't another place to put it.

A couple comments:

1) My suggestion for dropping haste for crit and mastery applies only in a very special case where you have the T11 4-set bonus but not sufficient other gear pieces to support the ideal haste amounts required for the ideal number of SSs per cycle. In that case, you are better reforging stats to support a cycle with one less SSs per cycle. Since that cycle actually requires very little static haste, you are better reforging for crit and mastery after meeting the haste requirements for that cycle. Haste above that requirement is still beneficial as long as it accounts for latency and human reaction time. Additional haste above that only benefits your autoshot and results in deadtime waiting to cast CS off CD. This case is definitely one well below the BiS case for which you provide data.

2) Were you do have sufficient gear to support the extra SS per cycle, then reforging crit and mastery to haste is beneficial but only up to the point where you can cast CS right off CD. Adding more haste beyond that point has no benefits to your special casts and only benefits your autoshot DPS while resulting in all of your shots doing less DPS or providing less WQs.

3) With that said, I do not really believe your plot that you provided. DPS cannot be a complete linear function with haste for several reasons:

- One problem is the range of haste you show. For the BiS gear set, the best CS rotation has 5 to 6 SSs depending on whether you cast a MMM proc AI that cycle or not. The ideal haste amounts to support this rotation is between 17.5% and 20.3%, which is a haste rating range of 2241 to 2600. This is well above the 1400 haste rating you show in the plot.

- The next is that you can't add more haste for free. Assuming an ilevel of gear, in order to increase haste, you have to give up other stats like crit and mastery and eventually agi. This tradeoff between haste and other stats is normally not a linear function.

- Even with assuming that haste can be added at no cost to other stats, here is the affect of haste on each of our damaging abilities:

-- Autoshot DPS does increase linearly with haste

-- KS is instant cast and costs no focus. So as long as we are casting it off CD, its DPS is constant with haste. In reality, its DPS will oscilliate with haste some as how haste affects the cast time of other shots will affect how much of a delay we have casting KS off CD. Regardless, it is definitely not a linear function. That's roughly 1% of my damage that is on average unaffected by haste.

-- SrS ticks are totally unaffected by haste. Thus, its DPS is constant with haste. That is another 3.9% of damage that is unaffected by haste.

-- CS is instant cast. The first impact that haste has to its DPS is resulting in enough focus to cast it off CD. As long as we have enough focus to cast CS off CD, its DPS is constant with haste. If we do not have enough focus to cast it off CD, then its DPS decreases linearly by the amount of delay time in its cast. The other factor is the delay in its cast off CD due to the duration of otehr shots casts. Once again, if we are casting CS off CD, its DPS is constant with haste with its DPS oscillating with haste depending on the resulting cast delays. This is another 13.3% of my DPS that is relatively constant with haste.

-- SS is affected by haste in two primary ways. The first is a linear increase in its DPS as haste reduces its cast time; however, once its cast time is down to the GCD (which only requires 1.46% haste from gear and Pathing during unglyphed RFs with the T11 4-set and 12.6% without it), its DPS is constant per cast. The second effect on SS DPS per haste is the haste points that allow an additional SS per cycle. These results in steps in SS DPS with haste.

-- AI DPS is affected by haste in complicated ways. Obviously, the MMM proc AI DPS is not directly affected by haste since it is instant cast and focus free and has no CD. How haste effects it is relative to how quickly your rotation allows you to do enough SSs to proc it. Hence, the DPS effect on the MMM AI DPS is definitely not linear since it is affected by the frequency of SSs (with is a step function with haste). Furthermore, when an MMM proc occurs is on a binomial distribution, which is definitely not linear. The cast AI DPS is affected by haste and increases linearly with haste up to the really high haste amount required to cast it on the GCD. But its DPS is also affected by haste in a step function where haste allows room and focus in the cycle for additional AIs, which is not a linear function as discussed previously.

-- WQ DPS is only affected by haste indirectly in that haste affects the number of shots we take, which affects the number of chances for WQ procs. Although haste does roughly linearly increase our number of autoshots to trigger WQ procs, this is not true with out specials. With a 1s GCD, we have a limit of being able to perform 1 special per second. Up to that limit, haste does not affect our number of specials linearly, it affects it in saw steps. For example, its requires about 20% haste to add an additional SS into the new CS-AI rotation. Up to that point where a new special is added into the rotation, haste has exactly no affect on our specials contribution to WQ DPS.

-- PS is also indirectly affected by haste. The PS tick durations are unnaffected by haste; however, how much damage each tick does is affected by haste in that being able to perform an extra special that procs PS per cycle increases PS DPS in steps with sizes depending on what additional special is performed in the cycle due to the haste. Even with a constant amount of specials in a cycle, haste still has some affect on PS DPS in that the damage will start a little sooner, but it is still the same amount of damage.

Thus, with all of these factors, I really see no way that our DPS can be linear with haste over the complete set of applicable haste ranges.
