I think I'll switch from AST to WHM. I have all three healers at 70+ and did play WHM here and there during SB but still have a few questions to improve my play.

1. Is there a number of enemies where Stone/Glare still makes more sense than Holy, or do you use it always if there is more than one?
2. Since Aero III is gone now, do you Aero II/Dia every single target or is there a number of enemies where you switch to Holy spam right away?
3. How often do you use Cure I? Does is have a place outside of "I am almost out of mana and this is the only way to heal now" (in other words when something went terribly wrong)?
4. Plenary Indulgence is basically for when I need all the AoE healing I can get?

Thank you.
