My personal thoughts with the augments included on the AF2+2:

Head: Okay, the Devotion augment justifies +2ing it.
Body: The regen improvement isn't bad at all, but SCH etc. Either way, it's worth +2'ing if one values Regens. I've always had Benediction heal for max HP across people, so I'm not sure what to think of the augment, really.
Hands: Worth it for the skill bonuses alone, depending. Martyr is situationally useful, but one won't really notice the boost.
Legs: Mandatory. Yes, that's right, I said mandatory. These are a mandatory piece of gear for any serious White Mage. If you don't believe me, go read about barspells and how effective elemental resist can be. That alone makes them mandatory, the Shellra V augment is just icing on the cake.
Feet: Hi enfeebling piece. Otherwise lol, even with the Protectra V augment, it's meh vs. AF3+2 imho, and if you really want MND, there's Marduk feet.
