I defnitely think if it had just the change of "healing actions" it would be really worth already.

Actually a side note, but the game really needs to improve the wording on Dissipation as well... currently it goes like " Also increases healing magic potency by 20%."... What is "magic" is kinda misleading, because stuff is labeled either Spells or Abilities. I speak for myself when took me a LONG time to figure on my own that "magic" only means spells and not abilities. Like, we tend to think most everything casters perform are magic, right?

Edit: Same goes for WHM's Temperance and probably something on AST being worded like that too.
