It used to be amazing in PVP before the 4.0 changes. For PVE I used it occasionally for solo content, particularly back in the job quests for breathing room.

And I suppose that's where it is still somewhat useful in group content; when things go south and the heals (if they're alive) or the rest of the group need a mob bound to a spot to give everyone a chance recover.

Otherwise meh; it can stay as is. We have enough in our rotation already, and I prefer for them to stop bloody touching NIN every patch.
