Well, I've tried, but the Lily mechanics are garbage. DB evaporates. Generating Lilys with another healer in the group is difficult at best, and completely distracts for doing useful things.

They could remove Lily's and Confessions and we wouldn't notice. We'd likely perform better as a result, too.

That's what they should do, frankly. Remove Lily's, Confessions, Divine Benison, and Plenary. Reduce the CDs on Assize, Tetra, and Asylum by 10%. Give Regen and Medica2 another tick or two. Give Aeros and Stone4 another 5 or 10 potency respectively. Now we're passive heals with oGCD top offs and a DPS focus... As they designed, intentionally or no.
