A bit of conundrum, with regard to the line about Regen. Does it mean that it boosts Regen on yourself or Regen cast on anyone? If its the former, that's pretty weak. If its the latter, it puts WHM one step closer to having Regen V without actually having access to it.
Also, with 13 MND and 11 Cure+, this piece just turned Orison into a macro piece for Divine Veil. That 1 extra point Cure can open up sets to sell off Fylgia+1 or Roundel if you still have it. That one extra point also becomes a factor for capping Cure+ more easily with Tefnut/Genbu combo.
And why not just say Regen potency like the merit and other pieces of gear do?
