Numina and Miracle Uniques....
Yes to Health. In Health, they will be active at all times. In Dull Pain, they will be active for 120 seconds after you trigger the power.

It takes some extreme circumstances to want the healing uniques in Dull Pain rather than Health. As Ironblade mentioned, in Dull Pain they will only be active for 120 seconds. Of course that's how long Dull Pain lasts for, and you may be slotted well enough to make it perma. But that usually requires many slots in Dull Pain (often 5 Doctored Wounds for the extra Global Recharge Reduction set bonus), leaving you little room for the uniques. Health however usually has plenty of room for those uniques, since at best you'll be slotting it with 3 Healing Enhancements.
There's a reason almost everyone puts them in Health. That's usually the best spot.
Goodbye and thanks for all the fish.

...should go into Dull Pain or Health?
It seems to me, they would best be in Health; just want confirmation.
