Performance Shift +End proc better than End Mod IO?

Okay, I've been playing around with Mids to see the effect of the Performance Shift +End proc set IO vs. a generic L50 End Mod IO. Each generic IO that I slot into most of the auto powers that take End Mod only seem to add about 0.075 end/sec to the Recovery rate. But if my math is right, the P.Shift proc adds, on average, 0.2 end/sec (20% chance to gain 10 end each 10-second proc cycle = 0.2 x 10 end / 10 sec = 0.2 end/sec).

If this is right, then it seems that the best thing to do is to put the P.Shift proccer in one slot of each and every auto/toggle that takes an End Mod enhancement since its 0.2 end/sec is quite a bit better than what any single L50 generic IO adds.

Do I have that right?

Oh, and is there any reason to craft or buy anything other than the L21 version of the P.Shift End proccer? It's benefits are the same regardless of the IO's level, right?

I guess this question also applies to any of the set IOs that provide a global proc (like Karma -KB or LoTG +Rech). Any reason not to get the lowest level version of these as well?

A proc will function the same at any level. From Paragon wiki:

However, the upside of Procs is that if the power is active, the Proc always work, even if you exemplar way below the level of the Proc. Procs don't follow the -3 level rule that Globals and Set Bonuses do.

Globals (like Numina's, Miracles and LotG) are dependent on level and will only work -3 to the level of the IO. For the case of Numina's and Miracles, this makes the lowest level ones most sought after. LotG, varies between people as it also grants + Def. Some people don't care and go for the minimun level, some people want more Def and don't plan on examplaring down, so go with the 50. Personally I shoot for a middle ground and tend to get lvl 30 or 35s.

Edit: Correction, after looking at Paragon wiki they have Numina's flagged as proc, with no flag on Miracle. I would assume they would both be the same since they do similar things. (Although this seems contrary to my memory, but I might check it out when I get off work)

Numina and Miracle uniques are indeed procs, not globals. This is why they almost always should go in Health or a similar passive - putting them in a healing power that isn't on all the time means you only get the buff while the power is on (for toggles) or for 120s thereafter (for clicks). It's also why their buffs stack for 120s when you zone.

The optimal IO slotting for Stamina is:

Performance Shifter: ENDMOD;ENDMOD/RECH;ENDMOD/ACC;+END

And yes, you do want to slot a +END into each passive Stamina-like power you have.

And no, I wouldn't bother with anything other than a level 21.

WARNING: I bold names.

I presume the only reason to slot up Stamina for four P.Shifters is to get the 2.5% Recovery set bonus? The Rech and Acc portions of two of those IOs is otherwise worthless in Stamina. Is that 2.5% really worth burning an extra slot in Stamina for?

For procs, the level is irrelevant, except for purposes of getting a potential set bonus. If you slot a proc,and nothing else from the set, the level can be 50, or 11, or anything in between and it will have the same effect,s o the only consideration at that point, is cost, which can vary a lot.

For globals, lower is always better if you plan to exempt, if not, get whichever is cheaper.

I've noticed that there are no P.Shifter +End proc recipes up for sale at Wentworth's, but plenty of folks bidding on them. I find it somewhat amusing that the L21 recipe sells for in excess of 100mil, while a L22 sells for about 1/4th that amount.

Which leads me to ask this: is there any way to specify a lower level recipe "purchase" from the Fort Trident box using Hero Merits? It only seems to offer current_level+3 recipes.

I usually slot performance shift Endmod, Endmod/rech (or endmod/acc, whichever is cheaper at the time) and the +end proc. I like the 5% movement speed bonus, and the 1.88% HP bonus is nice too. I really don't need the 2.5% recovery, as I can get that other places and it'll benefit me more with other powers.

Plus yes, all in all the +end proc is very useful, and the more you have, the less likely you are to bottom out your endurnace, even if your getting end drained (as each proc may tick every 10 seconds, but due to the 20% chance, one could proc on 10 seconds, another could proc at 20 seconds, and both could proc at 30 seconds)

You'll still want to slot at least two end mods into stamina and it's ilk, but you got the right idea about making performance shift: chance for endurance a priority. Generally I 3 slot Stamina for PS: Chance for Endurance, PS: Endurance, and a normal Endurance IO. This puts you at an ED suppressed enhancement value of about 95%. PS: Endurance has the same enhancement value as a generic IO, which is why I use it. Might as well have a small bonus to my movement.

Four slotting Stamina with four Performance Shifter IO's is actually *slightly* less effective than just using PS: Chance for Endurance and 3 generic end redux IO's, at least in regards to stamina management. You might consider it for the tiny HP and movement buff, but honestly, none of the these set bonuses on the Performance Shifter set are really worth going out of your way for, especially not at the sacrifice of something else. The only time I might consider Performance Shifter IO for its' set bonuses (outside of the Chance for Endurance proc, which is wonderful) is at the 6 slots, where the AOE defense might become an option for a soft-cap build.

Sorry, meaning that since I have an annoying tendency to go for months away, I 'm curious as to how many of my open orders got filled.

All of them? I can't possibly hope that I can craft them all and make inf. Can I ?
