Astrologian Speculations! How will it fit in?

[tjw]

The Astrologian in the Job Actions video seems to use the following abilities;

<Draw Card> And she seems to get an attack power buff.
<Activate Card>
Nocturnal Sect stance
<AoE Heal spell with shield effect> (the Diurnal Sect heal spell was shown in the PAX teaser, and had a star effect rather than shield effect. It also didn't seem to be AoE in the teaser spell, so with the more extravagant orbal effect above the Astro in the Job Actions video seems to imply AoE)
<Grand-Cross look alike spell> causes Heavy on target.
<Demi/Graviga> Most likely a quest ability, given the different pose while casting.

Now here's the interesting part that I think I saw:
<buff on self> But it's not active
<debuff on enemy> Again, not active until...
<activates both buff on self and the stun debuff on enemy>

So it seems that Astro can pre-apply buffs and debuffs, and then 'activate' them at the same time. Given that Astro uses celestial magic, which is commonly associated with time and space, I wouldn't be surprised.
