These objectives (below) don't describe why I selected AST, or those that I would want implemented in future- I would be more aligned with the changes to astrodyne, for example, card potency changes, or even consolidation to some OGCD heals.
A) similar APM to current day WHM.
b) A similar complexity to current day WHM.
c) A similar rotation to current day WHM.
d) A similar healer kit to current day WHM.
