Astro or White Mage ?

Synastry is on a 90 second cool down thanks to the last buff.

My bad, I forgot about that.
Honestly, the only thing that AST needs now is more control over their cards in my opinion. Not total control of course, that wouldn't fit well within the lore of the job, but still there's too much rng to make cards relevant for end game content.
Also...CO needs some love...really. As a healer it's pretty good now, even though Noct still fells underwhelming.
