Help SE with new mechanics for WHM!

[Omnia]

Lilly should not be RNG. Allow to be passive: (ie Lilly count 1/2/3 = 10%/20%/30%) increased heal (expended ONLY by one of the "new" skills). Confessions stacks should be permanent- and drops off when out of combat. If it MUST be RNG- then Proc Lilly from Regens/Medica at 10% if not 100% through direct heals. Anything but spell-speed though. AST just throws Spell-Speed away all day. no logic as the main tool of WHM

If all else fails....copy/paste from WoW.
WHM can have some Chains heals like Shaman- with a rework of Plenary Indulgence. They can adjust Confession to act like Priests Prayer Mending or even Atonement from Discipline Priests in World of Warcraft- dealing damage by healing or vice-versa.
