I feel like they made Lilies as a PvP thing then just tacked it onto PvE content. Lilies are great in PvP when the entire content revolves around spike damage and highly unpredictable damage so Cure, Cure II, and CDR start to become quite a thing to just help the WHM keep up with the explosiveness of the content.

I'm not holding my breath for any changes but it would be nice to see something for 4.4 leading up to the new raid tier.
