Great build! Works wonders with Cardiac, but you could go Spiritual Core Paragon and bump up your Regen and HP figures even more (1300% & 3322hp, for 180hp/sec). Should be plenty of recovery there to handle your endurance needs and it'd drop the recharge on Foot Stomp by a full second.

Not that much pure E/N out there in the game. Most attacks have at least some S/L component and you get the highest of your applicable defenses. If it is pure E/N, then 32% defense will help significantly and you can pop a single small purple to end up just a hair below the softcap (a hair above if it happens to be pure E/N melee)

You're arguing for most possible damage over time attributable to the proc and the proc alone. That's why you keep talking about it being a good thing if the AH-slotted attack does no damage. It's also where I think you're going wrong.

I'm arguing for least time used, encounter to encounter, as the valid measure. Do the same series of encounters in less time and you've got the better solution. I believe that the AH proc, similar to a Sonic cone, does the best in those circumstances. The more characters on a team, the more effective the AH-proc, again just like a Sonic cone.

Take the analysis to the solo context and I fully agree that the purple proc will be better and, often, a common proc may be better. With a team, though, -res is just too good a benefit to pass up. It's why debuffers are good in the game. They make everyone's abilities more effective.

PVE is essentially farming. You face large numbers of mobs in concentrated groups and you take them down in chunks. As with farming, AOEs are most effective here. The more powerful your AOEs and more plentiful your AOEs, the faster you'll go through those groups. Add AOE debuffs and you'll go much faster, especially a -res debuff because it adds the debuff percentage to your enhanced damage, not your base damage.

Now, if one team member leads with a -res debuff and the rest of the team follows with AOEs, you get a huge benefit and you get it immediately. You don't have to wait until the purple-proc-loaded AOE recharges. You don't have to wait a 10 full seconds to determine it's worth. You get to know right at that moment how good it is and it'll be really, really good. The AH proc is just a less-reliable (and often less effective) -res debuff, but it's one that anyone with the prereq powers can slot (i.e. you don't need an AT devoted to debuffing to get the benefit).

As a side note, comparing the AH proc to a purple proc is great if you're talking unlimited budgets and only purple procs. I'm still okay with it, because it is a theoretical competitor for a single slot in a single power, but rarity and price are something to keep in mind. A relatively small percentage of players will ever find a purple proc, let alone equip one.

Depends how much later and how many people benefit. One character getting off one hit in two seconds or eight characters getting off eight hits in two seconds. Most cases would fall in between. An extra 71.8 isn't likely to be the deciding factor, but an extra 20% across the board (and that 20% of real damage, not base damage) can be.

Hadn't thought about the Ice aspect, which requires a lot of defense-focused slotting to make it work. All that defense means less slotting for recharge, so a fast-recharge chain probably won't work out well. I believe the chain I posted requires around 204% recharge, which is likely out of the question in this case. Focus your IO slots on typed defenses and don't worry so much about a peak-level single-target attack chain.

Realistically, you'll be in crowds of enemies for everything outside of the occasional EB/AV/GM/Pylon. In crowds, AOEs are king. With three enemies in range, Burst will out-DPS everything else in Kinetic Melee. Look to APPs for a second AOE option. With two AOEs, plus the single target goodness of KM, you shouldn't have too many problems finding an attack to use.

FB has weak DPA, less than QS due to it's extended attack time. If you can get rid of it, then you're better off. My thoughts ran to: (PS) > CS > SB > BB > QS > SB > BB.

Mids has it giving 1.25% to S/L/E/N/F/C and 2.5% to each position?

If you're sold on Regen, then it's just a question of single-target damage and, possibly, mitigation.

I love my BS/Regen, but those big slow swings mean that you'll find yourself hoping from time to time that the attack will finish so you can activate one of Regen's clicks. Most of the time you'll make it. Sometimes you won't. If you want to PVP with this character, then go BS/Regen. If it's PVE you're looking for, then I'd recommend a faster set. That leaves MA from your list and it should be really good at bosses, elite bosses, and AVs.

If you're open to something other than MA or BS, then I'd recommend looking at Katana or Kinetic Melee. Katana will be great, with faster attacks than BS, plus the same defense buff. Kinetic Melee doesn't have defense buffs, but it is a great single-target set and it features stacking damage buffs. If you can stand the sound of it, it should be one of the better sets for pure ST damage.
