Prety much the same thing with otto irresistible dance. Now it's 13ish secs instead of 45 and you can't refresh the timer. In fact the only thing that hasn't change is song of capering, you can even cast it tru walls, save is incredibly high and the timer can be refreshed. However there's way to counter it.
DP (and the caster versions) is insanly unbalanced. I know PvP was never balanced but why make it worst. I think the best way to fix the problem is to block the spell from PvP.
