For a completely honest reply, I voted no. Skeleton form is there for a reason and its a nice distraction at that, However I would RATHER have a target circle added in like future EQ had. But yes chasing people in AoN is pretty annoying in certain areas, ie I chased beastagor thru KC underwater the other day and even after snare poison landing and him getting a shadowstep off by time I saw him in the water poison was off, and between those skeleton mobs on him(which do look different) it was still lol trying to look.
edit - as Knuckle just posted a prime example of pvp video,
