I guess I can see that in simulation FoF will do a smaller portion of your damage as you acquire more haste, but so will RSK. Those two spells have a fixed cooldown and are the heavy hitters but don't scale with haste, and ideally BOK should fill in the gaps in between. In practice I agree that fists of fury is harder to work into your rotation at higher levels of haste. Is the model trying to prevent haste capping and thereby reducing fists of fury usage to compensate?

I don't see haste capping as a problem unless you are playing a perfect rotation, which is difficult to do for a wind walker.

Somewhat pedantic, but it does reduce the time spent not autoattacking, which is effectively damage.

RSK will be top priority not just because of its amount of damage, but also because of the 15% additional damage from your abilities (which will scale with all things, but especially new mastery) - FoF does not give a similar debuff.

However, as others have pointed out, FoF should scale with all of our secondary stats. As Eeinx said, my assumption that it may fall off is at certain haste levels is flawed - even then, more testing required as not all energy capping situations are necessarily a loss (math and even logs have shown that using it at <85 energy is generally not a loss - perhaps even higher energy, but 85 is a nice, round number and a very safe one). Perhaps it IS because of Combo Breakers that the weird results are coming in - which just shows we need to test more in order to limit its margin of error.

I just can't see Blue deprecating something that they really seem to like as part of our rotation, and that they have engrained into the monk class (almost every monk NPC (drawing off of Shado Pan) uses it, so it seems like it is supposed to be iconic of WW in MoP). That said, even 200-400 DPS can add up over time - in a 6 minute fight, that's 72-144K damage (faulty math, I know, I'm just putting what 200-400 DPS is into perspective), which in some situations could be the difference between the top of the meter and the bottom of the meter (or, even, a server first kill ).

Also, thanks for all the comments on the guide so far. I haven't been feeling well the last 2 days, so I haven't really updated it since posting (I haven't even finished adding all of the sections). Feedback is appreciated, and outside eyes to review and make sure I am being concise is welcome.

The problem with using FoF isn't that the ability, when used at the right time is a dps loss, that question is easy to sim. The problem is that the complicated process of determining when and whether to use FoF during a fight is also a dps loss. There's certainly a haste cap, though rather high, where the superior damage per execute time of BoK outweighs the superior damage per chi of FoF, but there is a far lower haste cap where an actual human cannot accurately keep track of:
not dying and other vaguely important things like that,
if RSK is about to come off CD,
if you will have enough chi to RSK when it does come off cd,
if Tiger Power is about to wear off
if you will have a proc or chi to Tiger Palm before it does
if you are going to energy cap during FoF
if you are going to energy cap right after FoF because your next ability will also cost chi rather than energy
if TeB is going to wear off during FoF, or before you can refresh it given all those things above
if you have a combo breaker proc and will need to jab right after FoF to have chi to RSK, thus possibly wasting a CB proc
i'm sure there's more things I've left out

Given the accuracy of self assessment when it comes to video game skill, I imagine most people would find that trying to answer those questions correctly mid-fight each time FoF is off CD is going to be a far different dps cost for them than it is for simcraft. If you're ever wrong, we need to be looking at not only the dps cost of trying to think of the answer, but also the cost of answering incorrectly some of the time.

Given that the only real way to determine what the dps cost you pay to gain 200 dps, or 1000 dps, or whatever using FoF is for your gear would be a pretty exhausting amount of data analysis for fairly little gain, it seems a better pursuit would be finding ways to minimize the mental cost of deciding whether to use FoF. Feral druids have faced much the same issue with using Ferocious Bite, where often the mental cost to decide and the damage cost of deciding incorrectly, simply wasn't worth the damage gain of using the ability at all in most situations. A variety of projects to figure out what ability to use next have been done, though most druids at even a mildly heroic level pretty much just used them to answer the question of whether the many step check list for Ferocious Bite use had been met, or if it was actually better to just throw away a few combo points, wait a bit, and refresh Rip or Roar.

So, does anyone have a great system of power/weak auras, an ovale script, or something else that makes the FoF question easy enough that sub-perfect players can actually gain damage with FoF?

On a side note, there doesn't appear to be anything in the simcraft action lists people are pasting to address a number of the clauses I outline above. For instance if you have 3 chi and RSK is going to come off CD right after your FoF channel would end, that meets all of the conditions to use FoF, but then you won't have enough chi to RSK which will delay it, which is bad.
