I wasn't sure if the 75% thing was still true (it used to be, but that was a while ago and PvP is in a decent state of flux).

The fast animating attacks are actually a curse and a boon simultaneously. Quickly getting off multiple attacks gives you more chance to react with your */regen clickies as well as a greater chance to continue enforcing movement suppression on the target and greater proc contribution. Of course, it's similarly countered by the inability to get off a single big heavy hitter while your target is running away.

Confront/Calling the Wolf can be great for PvP with the -rng debuff, but remember that, if you get it, it's going to need to hit in order to be effective, so you'll want to slot it a bit (6 piece Mocking Beratement, anyone?). Web 'Nade is nice, especially since it takes the immob purple set, but the immob doesn't last very long (~4.6488 sec with normal slotting, immob resist is common and reduces it further), so you'll need to close quickly (SS +SJ makes it easier). Either could work. I'd suggest getting one or the other, depending on whether you want/like Weapon Mastery or prefer one of the other APPs.

Recharge, recharge, recharge, then defense. +HP is largely pointless because, with perma DP and the passive accolades, you're already within shin-kicking distance of the +hp cap. The tangential +hp bonuses from sets such as Mako's Bite and Touch of Death will be all you need to be sitting there at the cap. +Regen is also similarly less than useful because the increments are so tiny compared to what you're already packing. An extra .5 hp/sec sounds great whenever you're running around at 5 hp/sec base, but when your passive hp/sec is more than 50 hp/sec, and you can crank that up to ~200 hp/sec with your clickies (converting Recon and DP heals into hp/sec), .5 hp/sec is less than a drop in the bucket.

For your defense bonuses, go positional, with priority to melee over ranged and AoE. The bonuses are more common and benefits more broad. Touch of Death 6 piece in your ST attacks, Obliteration 6 piece in your PbAoEs, and BotZ 3 pieces in your transport powers.

Yes. The EndMod enhancement enhances the +recov from the Miracle and Numina's procs, allowing PP to grant more +recov than Stamina.

If you slot PP to maximize +recov, then yes. Of course, you use your tier 1 pick for CP to get even more recovery assistance. I'd actually be tempted to do this, especially since you can always use Tactics to do almost everything FA does (and what it does, it does better, for cheaper).

As to your problems slotting, it depends on whether you're talking SO or IO. In IO builds, I almost never touch FH or Resilience because the benefits of slotting them are so paltry in comparison to slotting up everything else (though I generally give them a second slot to get a set bonus out of them). Integration generally gets 3-4 slots, depending on the sets that I can fit into it. MoG gets 4 because it needs an LotG +rech and all of the +rech I can stuff into it otherwise. IH, DP, and Recon all get 5. That's a total of 22 slots for the entire secondary and leaves me plenty of slots for everything else. My primary uses up much more slotting than my secondary for all of my */regen builds.

I look like my avatar too, but that's because I swear that Edward Elric was based off of me... We act the same, look the same, and think the same...

As to PvP, you're going to want to generate 2 different attack strings. One which is cycled for long, drawn out fights against tough melees, and another that is short, sweet and eats the face of squishier characters.
The second one doesn't need to cycle specifically because, if you're using it, you should be having to chase your target down half the time and the other half you should be standing over their corpse if you manage to hit them with it. GD>GC>SD>GC will work for your cycling string, and, for your short string, GC>GD and GC>SD>GD should work well (which you use depends on how long you can ensure they'll stand there taking it to the face, remember that you just need to start the animation to get them to take the damage, so animation time only matters within the context of getting another attack in). Of course, BU should be interspersed as needed.

The reason why +def is seen as pointless in PvP is twofold: players have a base tohit of 75%, and players often have unholy gobs of +tohit and +acc. If you're packing 30% +def in PvE (a very respectable amount), a player attacking you will have a 95% chance to hit you if he's packing just 111% +acc, which is crazy common considering all of the set bonuses. The only characters that I would recommend slotting for +def would be power sets that already have lots of +def, and, because of that, get to run around with the sacred +elusivity. Elusivity, which is only accessible through primary +def powers in personal shields, iirc, is an end modifier that multiplies the end chance tohit by its inverse (re: 30% elusivity multiplies the chance to hit by .7). It's incredibly powerful. Of course, it needs to be because otherwise defense based characters would get eaten alive all the time. For more info on Elusivity, check out the Paragonwiki link, as well as the one on Attack Mechanics, paying specific mind to the fact that you're trying to avoid attacks from players.

For */regen in PvP, from what I've been told, your best bet to increase survivability is to crank out the +rech, +regen, and +hp, and ignore +def (except for the +rech being top priority in both, this is pretty much counter to everything I tell people about */regen in PvE). The +regen and +hp are needed to counter both diminishing returns and the -rech effects that will eat into your clickability (can't rely on perma-DP). The +rech is pretty obvious as to why. For offensive punch, +dam and procs are king.

Are you talking about the specific powers needed?

Ablating Strike > Vengeful Slice > Sweeping Strike

The great thing about it is that, if you toss in Blinding Feint beforehand, you get an excellent attack string with incredibly low +rech requirements.

BF: 12 sec base, 5.28 sec needed, 128% +rech needed
AS: 6 sec base, 5.544 sec needed, 9% +rech needed
VS: 8 sec base, 4.092 sec needed, 96% +rech needed
SS: 11 sec base, 5.28 sec needed, 109% +rech needed

I get neg repped rather often, though I figure it's because I refuse to behave in a diplomatic manner most of the time. I thrive on my conflict! Of course, I've gotten a surprising number of neg reps even when I was behaving in a civil manner just because I assumed that people were intelligent when I was making my post. Being neg repped because I didn't dumb down some analysis is just stupid >.<

Yeah, you would be able to run that smoothly. Would I want to? No. That's only 143 DPS. You'd do much better just grabbing Hasten and switching to the normal Storm>CAK>Storm>Crane attack string. Fire Blast is actually worse DPS than any of those attacks so including it isn't going to improve anything (Mids' doesn't calculate the bonus DoT damage correctly, it inflates the value).

Here's the an I15 MA/Regen build I made. It's not entirely up to date (probably going to ditch FA, Hurdle, Health, and Stamina for CP, Physical Perfection, Maneuvers, and Tactics), but it should show you something to aim for. You're definitely going to want to get more defense and recharge than your existing build had going for it. With defense, I generally recommend that you get at least 20% +def or don't bother. For recharge, more is always better. You're going to want to get 130% at the very least, just to be able to run the attack string I gave you, because Storm Kick might not have 95% +rech in some slotting set ups.

Okay, here ya go. Compared to the most recent build of yours that I could find, the only sacrifice is a loss of 10 hp/sec. The comparative benefits, according to your list of potential "sacrifices", are an extra ~1.4% +def, ~2.5% +res, ~1.9% +tohit, +2.2 mph movement speed, complete endurance sustainability without ever using CP, and ~5 points higher DPS.

As to the semantic debate, that is one of my primary hangups, especially when it's coming from someone that most people willingly accept build advice from. The manner in which you presented the information implied that any deviation from your original build, no matter how small the cost or large the benefit, was worse than the original, which is simply bad building. Encouraging bad design in that way is the reason why I "flipped out" (considering you were the one that said that it was pretty much impossible to make the attack chain sustainable without CP except by using suboptimal methods; I simply countered with math).

Are you talking about using a Storm>Crippling>FB attack string because the one you list is impossible, unless you found a way to have Storm Kick recharge as soon as you use it. If you're talking about Storm>Crippling>FB, the build you provided couldn't even run that because CAK would need to recharge in 2.508 seconds when it recharges in 3.45 seconds. Assuming you pumped the build full of enough recharge to run that attack string, you'd be getting 182.16 DPS, which is substantially less than you should be getting considering the investment to get to that point.

It would work for doing missions, but an SO build can run missions. It'll do slightly better than an SO build, but not by much.

I was applying that to me, specifically, as opposed to Scrappers in general. It's probably a popular sentiment that most Scrappers agree with, but I don't think there isn't a place for survivability focused Scrappers. Their place just isn't with me. I'd much rather get just enough survivability to survive, just enough endurance to be sustainable, and then put everything else into dishing out the damage.

You're forgetting that the 550 second endurance period was without any end redux. Getting the equivalent of a single end redux IO in each power (which is what most builds tend to manage on average) would reduce the costs down to 3.83 end/sec, which would give you 1.43 end/sec active endurance gain to play around with for additional toggles.

That depends entirely upon what your build currently has and what attack string you're running.

I use FA as another example of the horrible state of Scrapper APPs. Castle has told us that a power is supposed to get 3 times worse (ignorant of AT mods) when it converts from a normal power to an APP (the tier isn't supposed to matter). When you look at Targeting Drone (Blaster version; Scrapper version), you'll see that the Scrapper version is actually ~6-7 times worse (27% of the tohit and 250% of the endurance cost, but the addition of acc, which improves the tohit by roughly 20%)

And I know that the sacrifices aren't there, especially with the additional benefits of Physical Perfection. CP isn't nearly as necessary as you seem to be trying to make it, especially with the advent of Physical Perfection and the ability to super-slot the endurance recovery capabilities of the procs thanks to the presence of End Mod IOs within it.

With Stamina (Perf Shifter proc, Perf Shifter End Mod, common End Mod), QR (same as Stamina), Physical Perfection (Numina proc, Miracle Proc, Perf Shifter proc, Perf Shifter End Mod, common End Mod), and the passive +end accolades, you will generate 5.26 end/sec. Running all of the */WP toggles, the Fighting pool, and CJ would cost 1.55 end/sec without any end redux slotting. The BF>AV attack string would cost another 3.91 end/sec. That's a total of 5.46 end/sec without any endurance reduction anywhere. You'd be able to run for ~550 seconds before you run out of endurance. With 150 DPS, that's more than enough time to defeat an AV (~30000 damage overcoming regeneration). Endurance consumption for DB/WP is not an issue any more, if it was ever a major issue before.

It's much more likely that the additional cycles would be eaten up by NPC actions, since there are so many more of them going on globally for any time frame than player attacks. Keep in mind that attacks aren't the only things that the server is storing and constantly updating. AI determinations may be an even higher workload than calculating damage and storing hit points for NPCs.

I have looked at Kinetic Combat. In fact, I've made builds that use Kinetic combat. I still don't like the set because it's so low level and have such pitiful enhancement for everything but damage.

It's 70 base DPS compared to 75 base DPS and has 31% lower functional contribution from procs thanks to the longer animation time. The loss of 5 base DPS and a healthy bit from procs doesn't seem like much (especially when it's doubtful you'll be using many procs anyway), but, when you enhance it and factor in the substantially lower recharge amounts you'd be packing (50% uptime on SD compared to 85% uptime), it's going to generate ~158 DPS compared to ~185 DPS. They can both solo AVs, but one of them is going to be substantially better at it.

No, I never said that. Reread what I posted.

As a Scrapper, my first priority should be the ability to beat face in. If I'm going to sacrifice the ability to beat face in for the ability to withstand getting my own face beat in, I might as well just roll a Tanker and be done with it. DM/WP on a Tanker is actually quite powerful, thanks to the higher base HP. It's still going to be lower damage than the Scrapper, but if you're more interested in wrangling survivability than damage capability, what's the point?

I'm curious why you think there are that many sacrifices to make the attack chain sustainable? */WP is already packing QR, and the OP is going for Fitness and Body Mastery. He shouldn't have any problems with endurance, considering all of the passive +end he's going to be pulling in. He's not running Spines/Invinc or MA/Dark. He's running DB/WP. Endurance sustainability is pretty much a foregone conclusion once he nabs the passive accolades and the Perf Shifter procs, not to mention the fact that he should be getting respectable amounts of end redux slotting tangentially when slotting up his attacks. Going overkill on endurance won't allow him to do anything more. It would just going to sit there doing nothing.

I highly doubt that unless you're fighting enemies that resist energy damage more than smashing damage. Boxing's base damage is less than Charged Brawls (and I checked in game to make sure). All things equal, Boxing will always do less damage than Charged Brawl.

They might not be noticeable within the confines of a single attack, but the difference will definitely be noticeable across a longer period of time, such as an AV/EB fight. Losing nearly a quarter of a second for each attack is going to add up very quickly, especially when you're using an attack that deals less damage for each activation as well.

Are you endurance sustainable without using CP (possibly by turning off FA, which shouldn't be needed at all times, especially once you've gotten FU active)? If you are, then ditch CP. If you aren't, ditch SoW. In an IO build, it's less than useful since you'll already be incredibly hardy by virtue of set bonuses and sheer damage recovery.
