Let me make sure I understand the PS munching situation correctly and fully.
There are 4 situations where PS munching can occur:
1) SS->CS
2) SS->MMM AI
3) AI->CS
4) AI->MMM AI
According to my 378, 12.93% haste gear set analysis, each PS shot provides the following average PS amount:
SS: 5246
CS: 22761
AI: 24005
Over a 5 min fight, having 1 SS munched loses 17 DPS. 1 munched AI hardcast loses about 80 DPS.
With assuming a 40% crit rate outside the CA phase and a 100% crit rate during the CA phase, the chances for both shots being crits is 16% outside the CA phase and the following for each case in the CA phase:
1) and 3) 40%
2) and 4) 100%
Concerning SS->CS
- Assuming no CS glyph, the maximum number of these situations is 300/10 = 30 over a 5 min fight. The number is actually reduced some by the CS extension over the CA phase and when hasted, so a better number is 27.
- A portion of the SS->CS situations occur over the CA phase where SSs are almost assured to crit. With the shortened CA duration, there is likely only to be 2 to 3 CS casts over this period. With the 40% chance that both shots will crit, we are looking at about a 1-2 chance of SS PS mucnches by CS over this phase for about a 34 DPS loss.
-- The good news is that we will definitely prefer to be hasted with RF over the period usually. If we use the recommended 12.93% haste route, then the SS cast is at the GCD. Using the RF glyph or having a little additional haste above the 12.93% haste actually brings the SS cast down to below the GCD and eliminates the chance for munching during the CA phase.
- During the rest of the fight, there is 24 to 25 chances for for CS PSs to munch SS PSs. At the 16% chance for both shots to be crits, 4 munches are expected for an estimated 68 DPS loss.
-- The number can be reduced some by recognizing that this period includes the second RF pair and that the additional haste on top of it can eliminate 2 to 3 of the 25 chances.
-- With the increased RF haste, this leaves at most 22 SSs that could experience the munching. At the 16% simo crit rate, that is about 3.5 SS PS munches costing about 60 DPS over the fight. This loss is acceptable and less than the loss from delaying every CS cast a bit to try to avoid the munching.
- Also note that the adding of a little additional haste to make the SS casts during RF below the GCD also results in a little deadtime in the CS cycle during the Standard phase unhasted (when assuming latency is accounted), which can eliminate the munching then as well. With this being about 55% of the fight (with assuming the second RF pair is performed during it), this can eliminate another 13 SS PS munching opportunities. This leaves only 9 SS munching opportunities due to CS casts. With 16% simo crit rate, this is only a loss of 1.44 SS PSs or about 24 DPS.
- Thus, with a small amount of additional haste, we can reduce the DPS loss from CS PSs munching on SS PSs from about a 102 DPS loss to a 24 DPS loss.
Concerning SS->MMM AI
- With the expected number of SSs performed, I would expect about 17 MMM AI procs over the course of a 5 min fight. Thus, in the worse case scenario with all MMM AI procs casts after an SS and both crit, SS munching by MMM AIs will cost 289 DPS. With at most 2 of these occurring during the CA phase with 100% simo crit chance and the other 15 during the rest of the fight with a 16% simo crit chance, the more realistic case if all MMM AI procs are cast after a SS is 4.4 munches for a 75 DPS loss.
- However, there are many cases where we do not or can choose not to fire the MMM AI proc after an SS when taking advantage that the proc has a 8s window to use it. These include:
-- Some MMM AI procs will be used after a CS naturally since it just came off CD and is higher priority. That reduces the number by some amount. With assuming on average 3 discrete places where MMM AI procs would be used in a CS cycle, that eliminates about a third of the chances down to 12 remaining.
-- When using AS a the focus dump, the CS cycle always uses at least 2 AS per cycle when not using the CS glyph with the MMM AI replacing one of those. Since the casting of either the MMM AI or AS first can be done with no net impacts, we can choose to always cast the AS first followed by the MMM AI to further reduce the SS PS munching by MMM AIs. say by 5 as an estimate down to 7 remaining.
-- During the KS phase, as long as we do not perform any additional SS casts besides the second in the SS pair when the first procs it, we can wait to use the MMM AI proc until after a KS cast if it is coming off CD soon. If we have neither the KS or CS glyphs allowing for KS to be performed in a consistent location in the tight CS rotation, then we could choose to perform the KS in the middle of the rotation so that it is offset from the CS cast to increase the opportunity that CS or KS casts could be used to prevent MMM AI PS procs munching. Assuming that KS casts can be used to eliminate 2 munching opportunities, this leave only 5 total much opportunities. With assuming that still 2 occur in the CA phase and the other 3 outside it, this is a total of about 2.5 MMM AI PSs munching SS PS for a loss of 43 DPS.
Concerning AI->CS:
- We only use AI hardcasts during the CA phase and when under dynamic haste effects (such as RF, BL, or trinket procs). Considering some overlaps and accounting a little for having to use ASs instead of AIs sometimes, we only hardcast AI for about 2 mins of a 5 min fight, or about 40% of the time. Also with considering that during these phases, CS cycles are extended, I estimate only 8 of the 27 CSs being performed over this period with 2 of them in the CA pase. If one assumes all of the CSs are preceded by an AI, the total number of AI PSs being munched by CS PSs is about 1.12, resulting in an estimated DPS loss of about 90 DPS at worse.
- Considering the large focus cost of AI hardcasts, we normally cannot follow them with CS casts and usually choose not to. Thus, if we never follow an AI hardcast with a CS cast, the chance for munching here is 0 with a 0 DPS loss.
- Note that if we did allow for CS casts after an AI hardcast, that would reduce some of the possibilities for SS PS munching from CS casts.
Concerning AI->MMM AI:
- Once again we only use AI hardcasts about 40% of the time. Hence, with an estimated 17 MMM AI procs, about 7 of these at most would be susceptible to munching with 2 at most in the CA phase and 5 during the rest of the fight. This results in an estimate of 2.8 munches of this type for a DPS loss of 224 DPS, which is significant.
- However, this assumes that MMM AI procs are used after an AI hardcast, which should almost never ever happen for the following reasons:
-- MMM AI procs occur from casting an SS. When the proc occurs, the next AI cast after the SS should be an MMM AI cast instead of an AI hardcast, unless you are able to Q it and it goes through before the proc. I do not know how likely this is.
-- Some of the MMM AI proc casts in this scenario will occur after CS or KS casts.
-- Thus, for most people, I do not anticipate much of a DPS loss from this case.
Hence, I see the amount of total DPS loss from PS munching to be very small and not anything to really worry about too much. The amount of DPS loss can be reduced some by doing the following:
- Have a little over 12.93% haste from gear and Pathing in the 0 latency case and/or use the RF glyph
- Never follow an AI hardcast with a CS, especially in the CA phase. Always separate them by at least one SS.
- When possible, seperate SS and MMM AI proc casts by AS casts (when it is being used as the focus dump) or by CS or KS casts if they have come off CD.
- With the biggest chance of munching being during the CA phase with higher crit rates, pay more attention to these rules during the CA phase.
