In comparison to the SCH and AST job mechanics, WHMs doesn't feel very thematic to the job.
SCH has fairy guage, AST has a Card gauge but WHM only has lilies and it doesn't really have anything to do with a WHM. It's simply cooldown reduction for you skills that doesn't have anything to do with what a WHM is.

Do you think you captured the essence of what a WHM is with lilies?
