Since 5.05 revived AST as a proper healer. I got it to lvl 80 and play test for awhile.

Healing wise, AST don't feel weak anymore, so that's a good thing, but there are still some areas need balancing.

Single card buff that lasts for 15s is still a waste of my time. Outside of seals fishing for divination, my malefic IV matters more than single card buff on the right person. Once I no longer care to fish for all 3 types of seals, the require effort for activating divination with just 2 types feels both smoother and actual usage becomes quite frequent.

Noct sect is just as inferior as it were in SB. Shield value staying the same as SB is too weak for my taste. Neutral sect can basically cover the situation where you feel shield is needed. Diurnal Celestial Intersection's shield is almost always available to cover tank buster which eliminates the benefit of Noct AB. Ironically, Noct CI's 15s regen aren't really enough to heal for anything with it's 30s cd. Noct sect has been removed from my bar for now. If two diurnal AST can take turn to neutral sect, noct sect really doesn't matter that much. Noct sect needs a greater rework.
