Perf Shifter Proc: Maths are hard!

It seems like I read somewhere, that using the Perf Shifter proc is not a good idea if you're only one slotting the power and that you would be better off using just a normal EndMod IO instead. Seems like I heard that using the proc is only a good idea if you're using 3 or more slots, b/c ED would make the third EndMod IO less useful than a Perf Shifter Proc? True, False?

iow, if I were one-slotting Stamina, would I be better off with a level 50 EndMod IO or a Perf Shifter Proc? How about if I were two-slotting it? Three-slotting?

Short answer: Always slot the proc first.

It is always better to slot the PerfShift proc into Stamina. The very first thing you should put into Stamina is the proc, once you reach the level where you can.

At base endurance, even QR is better off with the proc. If you have the accolades or other +max end, it is ever so slightly better to slot the end mod IOs from lvl 35 on (or make sure to keep them at +3 SOs), but I think the utility of the perfshift proc outweighs the small end gain from the regular IO (when hit by a recovery debuff, the proc can still give you end, while the regular IO has in essence been stunted).

The various epic powers, Superior Conditioning and Physical Perfection will always yield more end (on average) with the proc than just end mod slotting.

If you are oneslotting the power, put a perfshifter in it. The average return is better than what you will see from a 50 endmod IO. Keep in mind that it doesn't give you ten end, it gives you ten percent of your total end.

Not that I'm saying go against the Proc suggested.

However, I will say putting just a lvl 50 ENDREC IO in the spot at least promises the .18 endrec.

I've gone 30+ seconds without any of my 3 +END Procs firing. So, the RNG can hate you at some points, and you sound to be relying on just 1.

That said, it becomes a personal choice imo. I'd suggest trying to find at least 1 more slot and 2 slotting for best of both

If you're hit by a -rec debuff and you're hoping the proc gives you that endurance, well... good luck with that. A blue insp is the most reliable of all.

I go for the "no variance" recovery buff of an end mod IO, personally.

If you get up to 4 slots it's best to use Performance Shifters: End Mod, End/Rech, End/Acc, Chance for +End proc. Slightly better recovery than three generic end mods plus the 0.2% average from the proc. 1.88% HP and 5% speed increase as a bonus

i personally prefer the proc, as most of my toons with IO'd builds have between 1-3 slots in there i usually always put the proc in first then see if i have room for more slots

i can get a LOT of recov from set bonuses if needed (i have a em/sr brute who is about 50% IOd and is sitting on 3.22 end/sec recov)

No, it's not better mathematically. Not when you advance up to a level of risk analysis. This is a more complicated subject than I am inclined to go into on the boards, at least with formulae and numbers, but suffice it to say, just because E(x1) > E(x2) doesn't mean x1 is implicitly better than x2, from a risk mitigation perspective. I'm not entertaining recovery being shut down as a factor because that's a rare and when it happens, as I mentioned above, a CaB is your best bet.

This by the way, is why I don't buy into "soft-cap or bust" conventional wisdom that pervades the game, but that's a different topic entirely.

A Performance Shifter proc theoretically gives you more endurance over time than an EndMod IO when slotted in Stamina or a similar auto power. However, exactly when that endurance is granted is unpredictable whereas an EndMod IO gives a constant recovery boost. Which is better really depends on the character and what you like to fight.

- If you expect to be at zero recovery often (for instance, if you have a nuke or other power that crashes recovery) then the proc is pretty much the clear winner.

- If you don't mind popping a blue at times or you don't run enough toggles to particularly care if your endurance hits zero then the proc is probably best since on average it does offer more endurance gain.

- If it's important not to fully run out of endurance and you don't want to carry plenty of blues then the EndMod is likely a better choice, especially if you drain your bar fairly quickly. The proc may give more average endurance over the course of a mission, but it is unreliable over a single fight which means that some fights you run out sooner than you would with the EndMod and others you run out later. By using an EndMod you know how long you have and can plan around it rather than hoping for a lucky proc before the bar bottems out.

- If you don't have any recovery crash and you can fully balance your endurance gain to your peak output with an EndMod (either through recovery alone or recovery plus an endurance granting power) then slot the EndMod. It's cheaper and you'd only need the proc when drained to zero recovery by an enemy... something that in my experience happens less often than having a blue pill drop so just pop a blue if it does.

Overall I'd go with two EndMod then the proc, simply because I prefer consistency to a a small but unreliable increase in recovery. The exception would be on a nuking Blaster who has an endurance recovery power... hitting Inferno and then having a the proc go off to power a Consume is a thing of beauty. It doesn't happen often, but when it does it's worth the wait.

My preferred 3 slotting for Stamina (if it's not a WP character) is to put a lvl 50 EndMod, the PShifter-EndMod, and the PShifter-Chance for +end.

If it's a WP toon I'll two slot Stamina without using the Lvl 50 EndMod. Depending on what recovery vs. end use numbers I'm getting I'll either use my standard Stamina 3 slotting above, or the two slotting here for Quick Recovery.

If I'm one slotting Physical Perfection I'll typically use the PShifter-Proc.

My personal experience is that the RNG is better to me with the +end proc than usual. It only gets better when you stack multiple copies of it. I've had characters that went from endurance troubled to indefatigable thanks to that proc.

The proc indeed works out to 0.2/s recovery...over time.

If you have say, a typical Energy Melee build, it can keep you fighting nonstop.

However, anecdote time:

I had a build for a SS/Inv Brute with a few +recovery values, but also a considerable rate of end consumption due to +recharge and a lot of toggles. With 2 Perf Shifter procs, that put him over the edge for end "recovery" where usually I literally did not have to look at his blue bar, ever.

However, regularly, due to the +recharge and timing issues, Rage's crash and Hasten's crash would occur near simultaneously. That is a big chunk instantly gone from your end bar. That caused toggle dropping more than a few times.

The procs works very well over the long term, but for sudden dips in end where you need to get it back quickly, it's not as great as more +recovery would be. Granted this is an edge case, but it illustrates that while the proc does average out to 0.2/s recovery, it's not the same as having 0.2/s recovery at the regular intervals.

If you are going to short slot stamina your FIRST concern should be to deepen your pool. The deeper pool leverages all your recovery values, increases the amount of Endurance for each Proc fire, and gives a bigger window of opportunity for the P-shift Proc to help you. And find a second slot for Stamina to place the P-Shift End Mod. I mean really, 2 slots in still pretty barren for that power.

Get the two +end accolades, Atlas Medallion and Portal Jockey, or the two equivalents red side, Marshall and Born in Battle. +5 Max endurance each. No, I don't think you can stack all 4 for 120, limit 2 per customer, thank you.

New Pool 110. New P-Shift proc value - 11 Endurance per Proc fire. 0.22 End/sec avg. Sight solving the avg. value of the P-Shift Proc is simple. Double your max endurance and divide by 100. That's why the old version of the Proc that alway gave exactly 10 endurance was always worth 0.2 end/sec avg.

Work some of the sets that grant +Max Endurance into your build if you can. Some of my favorites include Eradication at 2 slots but consider 3 for the 3.13% Defense to E/NegE, Decimation at 4 slots but use 5 for the 6.25% +recharge too, Gift of the Ancients needs 4 but has a Recovery boost at 2 paired with the +Max at 4, and even better, Impervium Armor at 4 slots with 2.5% Recovery at 2 and 2.25% +Max End at 4. The Mids Set Bonus finder can help as there are many others.

Get your Max End up to around 115 with the P-shift firing for 11.5 and a .23/sec avg rate. Even at full bore drain you should have a significantly longer time for the proc to hit you.

If you can get two of these procs into the build it becomes almost impossible to run dry unless you are drained / shut down. At least my Claws / SR with Physical Perfection epic can't. Runs Focused Accuracy full time too.

Hope that is of use,

Edit: never mind, ignore the below. The P-shifter is a chance to increase End, not recovery. The below is more like how the Miracle proc works.

Lemme make sure I understand how the proc works, because some of the replies seem to say the proc doesn't work the way I though it did:

When slotted into an "always on" power, like Stamina, the proc makes a check every ten seconds. If the proc is already on, then nothing happens. If it's not on, it turns on. And for 120 seconds gives the Recovery boost.

If that's the case, then it would hardly ever be off. It would only turn off if the check occurred at say the 120th second of the duration, it would be on, so it would not turn on. But then, right away the duration would expire, which would mean it would turn off for ten seconds until the next check.

So, tl;dr - the proc essentially runs for 120 seconds straight, then turns off for 10 seconds, then turns back on for 120 seconds straight, then turns off for 10 seconds, right?
