Would this be good?

It's really good and would not change anything.

You just helped me make a build for a healer.

I'd say try to roll with:

pain+(dazzling)
C - Savage blow 3
Seal - Savage blow 3

Having a -atk bane wont matter and you'll still find utility all around

All that fortress res.. ? so beautiful..

It brings a tear to my eyes!

This is not for azama, but warding stance 3 is generally better than fortress res for dazzling healers since you don't lose attack and get 1 res more; just thought I would put it out there.

Idk about obstruct....if u plan on using obstruct then martyr synergizes really well with it
