I love AST. ASt has been my favorite healer for a long time now but this current iteration with the recent buffs is really quite nice. I do think its too many OGCD's to a lord/lady card right now but theres very little I would actually change about the job. The things that /do/ ruffle my feathers is that dying on a trial or savage encounter is far more punishing as Ast than either of the other healers. A death at the wrong time means you group could lose out on an entire divination. Losing not only your cards but your seals is incredibly punishing. Imo you should keep seals if you die.
