Yoshi-P's Interview with Famitsu includes a few comments about AST

[Dyvid]

And just so you know, Aspect Helios is much more MP efficient then using double Helios if you do need that much healing. I would like to think most healers understand when they need to use Helios / Medica versus Aspected Helios / Medica II while they're dealing with party damage.

I'm about to step out the door for work but wanted to touch on this real fast. This is why Diurnal is better than Nocturnal right now, because you can over come the disadvantage of mp heavy HoT spells but trying to not over heal. When I play SCH I normally try to keep galvanized up on the party the whole time to make up for SCH lack of healing power verse WHM, that's what damage mitigation is about. You can't play that way in Diurnal Sect and you can't over come Nocturnal Sect inability to work with galvanized. The 5% healing buff is nice on Nocturnal but everything needs work. Until that happens Nocturnal Sect will not be good.
