I feel the Lilies should be used for something entirely different. Something to work towards. I came up with the idea of the WHM creating a stone statue of itself and placing it in the raid. This statue would then act as an extension of the WHM providing proximity based heals to the raid. The statue would switch from providing heals depending on what active buff the WHM activates. Shroud of Saints will provide MP regen to party members in range. Divine Seal with provide shields. Presence of Mind will speed up weaponskill and spellskill times to those in range. Cleric Stance will provide a DPS buff to those in range. The WHM could sacrifice the statue with three stacks of lilies with differing affects again depending on the active buff. Cleric Stance? AoE damage. Divine Seal? Strong AoE shield. Shroud of Saints? Large MP regen to selected target. It's not entirely thought out and I'm sure some of these ideas could definitely tweaked...
