Note also that any inherent crit skill will auto-crit its heal, too. Chaotic Cyclone's relative contribution is nearly as strong as before. Against even just 8 mobs, it makes for a 4800-potency heal. The difference is that the base is so much higher and it doesn't actually need damage; you don't have to hit for nearly as much to full-heal yourself, even in a single GCD, now as you did then.
In multi-pack AoE pulls, you effectively self-Bene with each GCD even without banked resources. Old Nascent was strong, but not to that degree.
This is only true if your ppgcd is under 800 (50% thereof being 400). But, IR Fell Cleaves are already worth a relative almost 950 potency, given its modifiers before accounting for crit chance value wasted. Primal Rush is a relative 1444 potency at a 1.5x Crit modifier.
Given that IR is now on a 1-minute cooldown, and you could certainly have an extra 100 gauge (or 50 + Infuriate, etc.) twice per minute, the new version is a decrease in sustain for single-target.
tl;dr: No. It's the opposite. Bloodwhetting's AoE healing floor increased greatly relative to old Nascent, as you'd not likely have been doing 800 relative potency per GCD per target. Its ST floor decreased, as you easily could exceed 800 relative potency per GCD in ST.
