So from what I'm getting from your first post. You want astro to become a very inconsistent healer that may or may not be in the right stance at the right moment? The way the game is right now, not only would that be incredibly difficult to balance but also the words inconsistent and healer are not something you'd want to have together in the same sentence. This is coming from a BLM main where I know how it feels to be caught in Umbral ice at just the wrong moment. Examples of this would be when an add spawns that absolutely needs to die instantly, but you are already out of mp and have to enter Umbral ice.
