Pretty much. Doing the math I found a MAX Crit build would theoretically provide the best Heal ratio. (20% Crit is pretty nice), but that requires T5 and you'll be using some expensive overmelded gear as well. My personal favorite BiS is the i90 full crit build, and that's what I'm sticking with. All other builds are equally viable, and really just boil down to what you want to do. the 5% crit over ~20 per heal from my crit build is valuable to me, but if 9% crit and 1k normal heals are enough for you then by all means go with it.

the only stats I consider really worthless are SS, and even that doesn't suck once you've got enough of it.
