Ok nice, I currently have two points in it which seems reasonably efficient for pretty consistent 30% inc armour and healing effectiveness
I've just got the build up to monoliths in SSF today and having heaps of fun, I found a nice Cradle of the Erased in my first mono with 11 WW and (not sure if this is SUPER lucky) hit t6 healing effectiveness for a total of 128%, I think it will go a long way for me.
I think the experimental glove mod is the cheapest way (in terms of item budget) to get the ward from Divine Barrier, it means you don't have to give up nice rolls on boots or chest. At level 60 and otherwise crap gear im sitting around 8-10k ward in my beam which is very comfortable !
