Street Justice Endurance Costs

I was just looking over some of the powers in Street Justice and attacks with the same damage and recharge in other sets and noticed something a little odd.

Street Justice - Heavy Blow: 5s recharge, DS 1.16, 6.03 end
Kinetic Melee - Body Blow: 5s recharge, DS 1.16, 5.82 end

Street Justice - Shin Breaker: 8s recharge, DS 1.64, 11.86 end
Broadsword - Hack: 8s recharge, DS 1.64, 8.53 end

At this point, I'm accepting on trust that there's a reason for this. But I'd sure appreciate it if someone with insight into the design of the set could offer an explanation for the additional endurance cost of these attacks. Particularly since Initial Strike and Rib Cracker are on par with other 3 and 6 second recharge attacks, respectively, and Rib Cracker at least has a rare and useful secondary effect.

Again, not complaining, just want to know the reason. No complaints about the set overall.

Maybe it's the combo system due to it generating 'moar damage'? I haven't bought the set but I teamed extensively with two SJ brutes while on my ice/time corr at level 25ish and I was very impressed how quickly they took down red bosses and orange lts. I was also impressed that both of them were complete end hogs with lots of endred and proper SO stamina slotting (I asked them, plus I knew the players and they know how to slot stuffs), they had to rest more than any Brute I ever saw/played except for a Stone Melee/Dark Armor, and my ice/time corr is already a major end pig, but they were worse in that regard.

DB gets endurance-free damage from combos, so does FM from dot ticks, to a lesser extent so do Claws/DB/SS/DM from their damage buffs, etc..

I don't think it's fair for StJ to have such a high end cost on powers. OP may have no complaints with the set, but personally I find it weaker and weaker the more I play it - and it's difficult to discuss that as people tend to be clouded by the fun they're having with it.

Going on a tangent here, but that attitude baffles me. We consistently get people who say "oh, I play for fun, not for power", but as soon as you suggest the set they're having fun with might not be that powerful, they jump at your throat. It's like they associate power with worth, which is a dubious attitude to me, even moreso in a video game.

Silly fleshlings. Nihiliibot enjoys StJ even though it sucks monkey coconuts.

I'm partial to Shield myself. That is, I would if I was a hypothetical person that didn't scream bloody murder about Shield GFX whether it's relevant to the actual topic at hand. Shield doesn't need +recharge either, and AaO is especially juicy with StJ for the reasons you mentioned ; I also tend to enjoy stronger aggro aura even more on quick animating powersets, as on higher (+) reps with WP, enemies tend to do the "I'm afraid/I'm taunted" dance a bit too often for my liking with the taunt effect from the aura not being perma anymore. Shield Charge fills the gap in decent radius, brainless AoE output.

I can confirm that the taunt component in EA does indeed work as intended. It's kind of weird, though. It makes things stick to you, but it doesn't make things pursue you if you brush past them while stealthing a mission, say. Not that I'm complaining about this, it's just odd. Handy though that EA's stealth power graphics suppress along with its stealth effects, much more informative than cloak of darkness. And cooler looking. Captain, a scrapper has decloaked off the starb-*gets roundhouse kicked*

SJ/EA is a great combination, though. Just got done with First Ward with only two slots added to secondary powers so far. Psi? Pfff, I guess that would be dangerous if anything lived for longer than five seconds. Going back to Paragon City is going to be akin to swimming over to the shallow end of the pool and wading around a bit of course.
