Astrologian Speculations! How will it fit in?

[Nihility]

Hopefully all is revealed in a couple days but as it currently stands it seems like

astrologian will have a basic small heal, burst heal, aoe heal, cleanse, raise setup like the other healers and the stance change just switches it between white mage and scholar style healing
Their utility and emergency healing like benediction, regen, lustrate, fairy healing, etc is a complete mystery and will likely be the thing that makes them stand apart from the others. Heck, the utility skills might be the thing that fluctuates with the stance even. Could very well have a simple cure/cure2/medica loadout and a set of utility skills that read like "create a barrier absorbing X damage OR heal X damage per second for 20s"

for the cards I'm thinking it will either be a 6 cards/6stats/6 elements thing and be like like the elemental staves in FFXI earth card gives a vit buff and damage reduction, ice gives int and magic damage boost, fire gives str and attack boost, thunder gives dex and crit chance boost, etc etc
Or they actually have 6 unique spells that require the corresponding card to use and a draw a card skill on a timer that lets them stock up cards
If it actually is set effects from a single card or combination of 2 cards your looking at a random pick from 42 different effects, kind of silly if you ask me

I would wager they have some non-random utility as well. Time mage effects like haste/slow/blink don't seem too far fetched either
Selene effectively has AoE haste in every sense but the name yet no one makes the association

their offensive spells appear to be ice and thunder based which i guess is pretty cool.
