Is this a bug?
This has happened to Mesmer since BWE2 (Beta Weekend Event 2). During that time, it used to be a target skill (not a ground target) that dealt more damage than it currently does. You could also use it while moving without stopping. Apparently that was too strong (probably was), and so it got hit by nerfs in all directions, as per Mesmer standard.
It’s not a bad skill, but you get used to it. Also the stutter is pretty small (it used to be longer, iirc).
Geez, I hadn’t noticed it before
