This is the wrong way to nerf it. Blinding Light will now be used excusively offensively, just opening the paladin up to another interupt (that most likely won't happen, as those who allowed a paladin to do repent>HoJ>BL>repent already weren't taking steps to stop the paladin. All you have to do is switch to the paladin), and BL will never be able to be used defensively optimally. Consider a time when two melee are on the paladin. Will the paladin try to cast a BL? He'll have to juke a kick. If he did that, he might as well spend that time trying to juke a kick for FoL.
