How will NIN nerfs affect them?

[Valenth]

It was also bugged and dealt physical damage, which dripping blades and slash debuff increased. Now it's magic and doesn't receive bonus from those. So it was actually nerfed. :/

Yup, they essentially decreased it's output dmg by 20% despite the potency buff (which was a 10% buff). I wished I had played NIN before it, wondering how strong those Bhavacakra's back then were. xD
