:: Correction from before: I'd meant to write "ceiling", not "floor" for what decreased for ST. The ST floor went up, greatly decreasing the penalty for mismanaging Bloodwhetting windows. The ST ceiling decreased. Both the AoE floor and ceiling increased.
The floor is higher (again, my bad on the typo), but the ceiling is lower, especially in the current contexts of modern IR. Again, Fell Cleave does a relative 950, for ~19% more healing per GCD than the flat value. Inner Chaos does 1340. Primal Rush does 1444. At two Bloodwhetting casts per minute, you essentially need never drop below an average of 1000 potency per GCD for the length of Bloodwhetting, meaning you'd get at least 20% more healing from a percent-of-damage design than the flat heal per weaponskill hit.
Imo, that leaves the new design, the flat heal per weaponskill hit, overtuned in AoE (and relatively undertuned, compared to said AoE capacity, in ST). I'd much prefer the healing scale as damage does--i.e., not be linearly increased by target count. Such is more intuitive, even if it does remove some super niche cases (my healer is dead in a dungeon and I mismanaged CDs) to make two-target AoEs preferable to ST damage.
