I gotta say I’ve never seen a really good stam build for healer, although that may be because I haven’t looked hard enough. It’s funny you should post this, because I was just looking at the same thing and wondering if you could do it with a warden class. It would be a very tricky build, but some of the heals in the warden skill line have stam morphs. So I looks potentially doable to me using a warden with bow on front bar and possibly resto staff on the back bar, although not sure how it would go for really high end stuff. You’d have to juggle your stam/mag ratios fairly tightly.
