I think your main issue is just focusing on the change made to Hungering Blade while not taking the other patch changes into account. Critical damage on shotguns was removed and with the change to special ammo you will find yourself facing a super with your primary. Yes, team shooting does occur but that stopped regen anyways at least now you will get some health back.
But that's the same with literally every other super. You won't have a sniper or a shotty to deal with your sunbreakers, stormcallers, self-reses and golden guns.
Besides secondary spawns every 60 seconds there will not be any shortages whatsoever. It will be more of a reason to camp at special.
EDIT: I get your point though. We need more info, and the patch in our hands.
Yeah. Supers will actually be very durable now. You won't be domed or shotgunned as frequently now. I believe this is the main reason for the blade dancer nerf. If you are in a crowed and nobody has a shotgun you will dominate. Now if they should have tested the waters before they did this nerf is yet to be scene. We will find out Tuesday.
