My basic assumption is that while healing one would have Julianos to bump the heals and on the DPS bar you would have Kagrenac just in case you needed to resurrect someone, but still do respectable damage.

Kagrenac's
(2 items) Adds 967 Max Magicka
(3 items) Adds 129 Magicka Recovery
(4 items) Adds 1064 Max Health
(5 items) Increase Spell Damage by 224. Also, decrease time to resurrect an ally by 25% and restore 1720 Magicka when you successfully resurrect an ally.

Julianos
(2 items) Adds 688 Spell Critical
(3 items) Adds 967 Max Magicka
(4 items) Adds 688 Spell Critical
(5 items) Increase Spell Damage by 299
