Proc DPS Question

So which would I benefit more from as far as DPS is concerned, 2 Chance for BU procs, or one Mako damage proc and a Chance for BU proc? As of the moment I have 2 BU procs, but I can easily switch one out for the Mako.

Oh, sorry. I'm running FU > Slash > Focus > Strike on my Claws/SR.

And what +dam amounts are you currently running? Do you also have the AH proc in Slash? Assuming you're running ~95% +dam in all of those attacks, and you've got the AH proc running, then you're better off taking the BU proc.

FU>Slash>Focus>Strike would generate 2 stacks of FU for all powers (the second stack will fade on FU while it's still animating, but that still counts fully so no loss) and 6.9% -res from the AH proc for all of the attacks (gotta love that 10 second duration, no?). -Res is going to increase any additional damage from procs just as much as it would +dam so we can ignore that. Each attack is going to have ~175% +dam (75% from FU, ~95% from slotting, ~5% from the BU proc), so the question then arises as to which would be better: an additional 4.86% +dam (1 - (.95 ^ (1-/5.28)) * 5.25 / 10 * 100) or an additional 14.36 damage.

First things first, 175% +dam for that string would give you 227.7 DPS (1202.3 damage over 5.28 seconds; assuming 100% hit rate). An additional 5% (rounding up because it's late and I'm feeling lazy) would give you an extra 21.86 (base damage * .05) damage per string iteration. The Mako's proc (because there's only a single check per string iteration) would give you an extra 14.36 damage (71.8 damage * .2 proc rate) per string iteration. 21.86 > 14.36. BU proc wins.

I know you asked from a dps standpoint, but just to keep you from being mislead...

I'd like to add (since I was just using the two BU proc recently then respecced out of it) that outside of 'perfect DPS' that is, outside of times where you'll be fighting AV's or Pylons. BU procs going to underperform nearly everytime you get lucky enough for it to fire.

The reason being that the buff starts right as the damage lands (not necessarily the animation), and only then lasts for 5 seconds. Meaning that you lose a significant portion of buff time to animation time. Also, if you have to switch targets/find a new target, you'll likely only have time to use one buffed attack. Where as with the proc you get 100% performance always. (Whereas 'Boost Up' proc only pulls ahead when attack chain finishes without interruption post proc)

I would suggest using ToD: Chance for Neg energy in follow up (not expensive) and the knockback set chance for smashing damage in focus.
That allows you to vary up your damage type a bit, which is nice since lethal is so heavily resisted throughout the game.
When you can afford the purple procs get them, they are great things.

It's up to you, but the relatively small DPS difference may not be enough of a trade off for an actually perceptable loss in regular content. <unless this is a dual build specifically designed for this role.>

Thanks! I was going over this exact question for my dream claws build (BU procs vs regular).

I like to use my Scrapper mainly for AV's/Pylons/etc. It's fun taking down the bigger targets, so I'll keep the BU procs in. Besides, with double-stacked FU all of the time, most of what I attack is dead in a few hits.

Ah well then by all means I suppose after a certain point of IO'ing on a scrapper (unless specifically farm built) the game outside of EB/AV's and Pylons gets sort of dull. So I understand where you're comin from.

So who wants to be the one to tell Werner he has to update his Claws DPS spreadsheet since he didn't use the buildup procs?

I gave it a half hearted try, but the math debuff wouldn't stick and the excel formulas kept giving me grief.
