Should WHM get a personal damage buff?

<Edited for clarity of context>

With cure 3 and thin air, I find it hard to believe it will ever be out done in healing potency.

If a pure HPS advantage is what WHM identity is to be based on -- which is the question here, at the moment: one of identity -- then consider:

In terms of potential burst, a crit Deployment more than gives WHM a run for its money, especially now that Sacred Seal is gone. On a Warrior with Convalescence, Minne, and either a Mantra or Fey Illumination, that's a 1344+ potency AoE shield. Earthly Star, Lightspeed Noct Helix x2, and Collective Unconscious can likewise put just as much healing/shielding burst as a Cure III spam + Asylum + Assize over the same amount of time.

Among optimization tasked to spend the fewest GCDs possible on heals, the sustained HPS of WHM means less and less. Much the same can be said of Thin Air (over)heal potential.

And speaking of sustained, Noct Aspected Helix cuts a middle ground right between Medica and Cure III, but has the added advantage of an eHP bonus over Med and a whole lot more range over C3...
(And then there's the far more reliable, and instant, 700-potency heal-shield to step soundly atop SCH's toes in the absence of the 'original shielder'.)

Edit: My apologies, I forgot Noct A.Helix uses a reduced potency. It's merely 431.
