Regen and HP for Night Widow

I'm trying to make my Night Widow build more survivable for long fights, such as soloing Rikti pylons and AVs. Pure defense isn't reliable enough, so I figured I should try adding more regeneration and HP.

Here's an experimental build I made that's similar to my current build; I replaced dart burst and eviscerate with dark obliteration and summon widow and also moved some slots around. There's only a 3 hp/sec and 33 hp difference, though.

Is it worth trying to go for even more regeneration/+hp? would have to sacrifice a chunk of recharge. I was also thinking of buying the Panacea unique and slotting it in health.

Well, one thing that immediately comes to mind if you want increased survivabilty is to pick up aid self. Sitting at the def softcap you are not going to have any trouble getting off aid self and the heal you get from it will beat any amount of regen you can get through set bonuses.

Looking at your build you could easily replace placate and summon widow with aid other/aid self. Placate really isn't very usefull for a widow - you don't do enough crit damage to justify the time spent in the animation, you are far better off just hitting another attack and none of the pet summons in the PPP's are really all that great - the summon blaster power (mace mastery) conjures a decent combat pet and the mu master pet at least heals but the widow is quite skippable. Stick a doctored wounds set aid self and you can even pick up an extra 5% global recharge and get a 38% heal you can fire off every 5.5 seconds.

I was considering choosing the medicine pool, but the activation time and redraw turned me away. For x8 missions, medicine would be perfect, but for tests of DPS like AVs and Pylons, passive survivability is more favorable.

I'll try a test build and see if the activation time is really as bad as I think it is.
