The character I've played most, both overall and in incarnate trials, is my SS/EA brute, so since nobody else has jumped in I thought I'd offer some thoughts. (Note: I said this, then typed a dissertation. Oh well...)

My general opinion is that because you will never be called upon to solo an iTrial, building for the iTrial soft-cap isn't usually worthwhile. Even running through the "gather" portion of Lambda, I rarely have trouble (the lowest of my non-Psi defenses is +50.6% without Energy Drain), and when I do a purple insp takes care of most of it. The amount of +def flying around in those trials, from incarnate powers and other various buffs, is ridiculous; my squishies often pass the incarnate soft-cap!

Assuming you are committed to that route, though, there aren't a ton of things that there's even room to change. A few jump out, though:

1. The second piece of Steadfast Protection gets you minimal added resistance in Energy Protection, and the set bonus you get from having it there is lower than the set bonus you'd get if you used the slot to put a fourth piece of Performance Shifter in Stamina. There are other things you could do with that slot as well, probably.
2. The Kismet unique is not needed in this build (because of Rage). The slot would be better used elsewhere. If you're going to 5-slot Taunt, for example, you might as well take the Kismet slot and get the 7.5% recharge bonus for Mocking Beratement. (If you're worried about the rule of 5, don't; the LotG bonus is a separate named bonus from the 7.5% you'd get from something like Mocking Beratement or Basilisk's Gaze.)
3. Taking Jab just to slot Kinetic Combats in it is a waste of a power slot; you could slot those same 4 Kinetic Combats in Boxing, which has higher base damage and is negligibly different on recharge and end cost. Dumping Jab means you could take some other random one-slot power later on. Assault or Tactics are worth a glance, and Darkest Night, even with just an end reducer in it, synergizes very well with this build. And since /EA can still experience cascading defense debuff failure, having Overload as an "Oh crap!" button isn't terrible.
4. Speaking of Basilisk's Gaze, you could modify the slotting on KO Blow to use 2 Basi and 4 Mako (or any other damage set, really; the 4 Kinetic Combats could go here and you'd have 3 slots you could use elsewhere - like Darkest Night, if you went that route, since 4 pieces of Dark Watcher gives nice bonuses) and have better e/n defense, since 2 Basi gives you 2.5% and 6 Mako gives you 1.88%. You could also go nuts and slot 4 Basi and 2 level 50 Damage IOs boosted to +5, but I don't get the impression you're concerned enough about maximizing recharge to do that.
5. I'm curious why you went with Soul Tentacles over Gloom. I've played with Soul Tentacles on my SS/EA, and the 25-degree arc on the cone doesn't synergize all that well with your other two AoE attacks, Foot Stomp and Dark Oblit. Plus, Gloom is AMAZING and something I can't imagine not being part of my attack chain. Gloom also takes Thunderstrike, which gives you you more E/N defense for 3 slots than you get for 6 with Trap of the Hunter. In fact, 6-slotting Thunderstrike in Gloom would get you 3.75% E/N, which probably frees up some slots elsewhere. For example, that 6th slot would mean you no longer have to shove 3 Erads and 3 Cleaving Blow into Footstomp, so that you could (for example) add a fourth Erad (for the big +hp boost), the FF +rech proc (amazing in FS) and something like D/E or A/D/E from another PBAOE set to flesh out the power's stats. Yeah, you lose a little recovery, but you have Energy Drain ready every 17 or so seconds; recovery should be the last of your worries.
6. Depending on what you want to spend, a set of 5 Panacea (no proc) in Energize is also nice.

Anyway, that's what I can see that could be tweaked without changing the focus of the build away from having iCap defenses. The important thing, in the end, is that you're happy with it and end up with a character that's fun for you to play, so please feel free to disregard anything I suggested that doesn't mesh with your playstyle.

I was looking at this last night on beta, where I have a set of 5 that includes the proc slotted. The only piece I don't have slotted is dam/rech, and I've catalyzed all 5.

The bonuses from those 5 enhancements (4+proc) still have me at +96% damage, which is the only thing slotting-wise I gave up to put the proc in. (The recharge may be slightly lower, but because of my alpha slotting I'll never be able to tell...)

If the proc does anything at all to benefit my other attacks (and I have a difficult time imagining it does nothing...) then it's probably still a better option for me than the dam/rech piece.

Is it an underwhelming effect? Sure. Is it something that I'll still slot before the dam/rech to get to 5 slots? Probably.

That is freaking spectacular.

You know what I'd like to see fixed?

The use of "really" as a repetitive rhetorical question.

Really.

I had snowmen in the LW map drop purples twice last night (one Absolute Amazement, one Armageddon). Another teammate got one as well - pet set, I think.

The only thing the snow critters inside instanced maps from Father Time don't seem to drop normally is enhancements. Everything else is standard.
