Although Earthly Star doesn't have cast time it's really nothing to count on if you need a quick heal. Even when it's already set up it takes time to explode and heal the target after you do the healing casting animation. It's a really good skill (even debatable that a bit OP due to potency) but certainly not an instant heal like Assize or the Scholar one.
