Is there official (i.e. developer) information on the behavior of this attack? It seems useless as an ability due to the following facts:
  • It does not place you into melee range at the end of the attack.
  • It does not leave your "hitbox" at the starting position (i.e. like a normal ranged attack).
  • It's animation lasts longer than the global cooldown.
  • It locks you into the animation and prevents all other abilities for the full duration of the animation.

Is it just a broken power? How was it originally intended to be useful?
