I'm gonna post something I posted on Reddit earlier.

By granting Cure 2 a 100% proc rate to lilies, they made the system even worse. One might ask, why? Having lilies come 100% from Cure 2 takes away all the incentive from using Cure 1.

Cure 1 was previously used to fish for Freecure procs, due to MP "problems" WHM had, but now, with the addition of Thin Air and lower CD on Assize, as well as a buff to Shroud (now called Lucid Dreaming), you'll be better off by letting the tank get a little lower and only using Cure II, because the higher MP cost by doing so will be compensated by consistently having Assize on a 48 seconds cooldown.

Keep in mind that ASTs still have the incentive of Enhanced Benefic to be casting Benefic 1 - wich grants a 100% crit on Benefic 2, also reducing the cooldown on Lightspeed by 5 seconds.

The right course of action in my opinion would be to give Cure 1 the 100% proc to lillies, while reverting it to 400 potency.
