Steps:
1. Cast Benediction
2. Just walk or move; the animation will cancel.

So this is kind of a weird bug. So after playing WHM for so long, I was wondering why Benediction felt so underwhelming compared to Tetragrammaton, Afflatus Solace, Afflatus Rapture, and other instant-cast WHM abilities. Turns out, the animation cancels completely when moving. This is unlike the aforementioned skills which "slide-cast" the animation until either the animation completes OR if another ability cast cancels it.

Before the review team dismisses this as working as intended let me clarify. When animations cancel, they usually cancel because of other abilities or casts. Animations also cancel if there's a cast time like Cure, but you move before the spell completes casting. Benediction is neither: it is the only instant cast skill in the game which the animation cancels completely with any movement.
