I recall a GM post in regard to DFA spells that stated something to the effect that it was never intended to have any attack test against just one defense. That it happened at all was a mistake in the first place.

I did not get the chance to ask, I figured someone else would at the meeting.

Has there been more consideration to creating some sort of Esoteric Augmentation that would prep/cast/harness/cambrinth our other augmentation spells into one? Having to split the mana between each spell you want at the time of the cast. Or charging some sort of special holy orb/icon with mana to cast them when needing them up in a hurry. And then having to recharge the orb after so many uses?

Essentially creating a "Battery" spell, or more aptly a "holy crap I am swarmed and need my defenses up cause they fell off at the same time" spell.
