Not a chance.
The whole point of Misery is to refund the DPS lost by using Rapture or Solace instead of Glare. As long as Misery is the action unlocked by spending lilies, it would be simply absurd to have a DPS lily option.
As long as shields are on the GCD, pre-shielding will never be an effective healing style. Shields are only meaningful if an unshielded hit will KO someone or if shielding prevents a fight-losing debuff. If everyone has enough HP to survive without shields and there are no critical debuffs to block, it'll always be more effective to use regens or oGCD heals after the fact. And because light parties only have one healer and the DF will probably not force regen+shield healers except in Raid Finder, every non-Savage non-Extreme non-Ultimate fight has to be survivable without shields.SCH:
create more dependence on shields. Shield healing used to be a healing style but with how effective its oGCD's are and the lower healing requirement shields end up being a safety buffer or a niche use and not a healing style. This I feel will be a NECESSITY with the upcoming shield/pure healer divide for it to work. Make SCH a true Shield healer again, it is currently a pure healer with extra shields.
