Devouring Orb is a strong and fun skill, especially with the Dark Moon mobility-oriented branch. But as my grandpa would say “that boy’s got a hitch in his gitalong” every 4 seconds when it recasts. The jerkiness is especially jarring after playing an auto-Maelstrom Shaman which has a similar playstyle and does offer an instacasting node to remove the hitch.
Please add a node near Sightless Star to remove the casting time completely.
