Then what would you say? O_o

It's the end. But the moment has been prepared for ...

This. EA is fantastic.

A +rech power, a defense cushion power(you can reach the incarnate softcap with it), endurance management, and a self heal?

Sure it has a psi weakness, but in terms of offensive capabilities it beats all secondaries.

Energy Drain will help with reaching the Incarnate softcap but you still have to work for it. A fully slotted Energy Drain + Agility T4 will give you 7.78% defense after hitting 10 mobs. Not enough for most Incarnate situations, even if you're sitting at 45% defense already. Personally, I just went straight for the Incarnate softcap with IOs. Energy Drain in my build is just a mule for LoTG and there for endurance emergencies.

No clue where you got the idea of EA having the strongest offensive capabilities. SR and ElA get the same 20% recharge bonus if that's what you're talking about. Defensive maybe? Even then, it's arguable.

Energy Drain stacks with itself(except for the first target which grants the most defense), and can be used twice in one duration, so you can get there without any special tricks. Granted you won't be there constantly, but if you want EA to put you at the incarnate softcap with one application, you can do it with IO's(which has become easier now with Stalker's Guile and the PVP +3% def IO becoming cheaper).

SR has to rely on Rebirth for self healing and has no endurance management tools, so it can't afford getting Ageless and an offensive ancillary(not body mastery) like EA can. Defensively, SR has far better protection against exotics and better DDR, and with Rebirth its self healing is almost on par.

ElA has to get defense bonuses from IO's to catch up with EA, so it can't afford to get as many recharge and damage bonuses from IO's like EA can. Defensively, ElA has resistances to fall back on which EA doesn't, which means that after getting a lot of defense IO's, its defense is superior. It also has solid protection against psi.

So while both SR and ElA have a +rech power just like EA, they don't share the same offensive potential, but make up for it with better defensive potential.

Good points. However, SR can hit Incarnate softcap without Agility which leaves room for Musculature, at the cost of 3-5 seconds off of perma-hasten. At 59% defense and perma-hasten, the only benefit EA really draws from Ageless is the +DDR, which brings it up to almost SR's level in that field. As far as EA having more offense from ancillary picks, SR can just take Spring Attack. The ancillary ST blasts are hardly worth it and there's usually not enough slotting to have both Spring Attack and an ancillary AoE attack. EA will have the option between the two but it's hardly an offensive advantage.

Not much disparity in offensive potential between SR and EA, really.

This is assuming you don't gain anything from recharge past perma-hasten, which isn't really true. And I didn't even think about Agility, Musculature is the only way to go IMO.

EA can take Spring Attack as well. When I said ancillary picks I pretty much meant Water Spout and Pyre Mastery.
