Rune Advice Needed
I run the shouts build 0/0/30/30/10 with mace shield/staff . I played around with runes quite a bit awhile back and found boon duration to be to my liking. Swapping mace/shield/Hammer can give pretty much 100% up time on regen and protection. As it were I cant stand the hammer.
For the healing part with your gear choices, it has been my experience +healing power is all or nothing. I run full cleric’s with the head swapped out for shamans. Gives me ~15K HP-1970toughness. Healing power is something like 1370 and I use a sigil of life on the staff to get the stacks.
I run Dwayna2/Monk2/Water2. From what I can tell Dwayna does not increase regen duration but does change the amount healed on the tool tip. I am also pretty sure boon duration doesn’t correctly affect boons from symbols, though its hard to tell since they are so short.
TLDR; I don’t think you have enough sources of boons without shouts to benefit from Forge/Dwayna on the defensive side. Divinity is also relatively low defense boost. I don’t see anything other than vit/toughness really adding anything for you other than proc effects you really cant count on.
