Given that enemies will be doing less damage, how do you know such a passive would eve be necessary post 1.03?
If the damage in inferno is going to be do devastatingly neutered then it will be nigh gutted for the classes that currently do scale well with their percentage based defensive increases. Currently WD and DH are sort of lacking in this area.
But if the inferno nerf is that severe, that such a passive isn't necessary, I'd probably be upset that they over nerfed it.
I don't want a cakewalk, I want a chance for stocking up on ilvl63 perfect roll items in every slot and ceasing to become a class that relies on these 'burn your discipline on these short duration defensive abilities then die when you run out of disc' builds.
