There's not much we can do but await a response at this point since I think everyone's covered a lot of weaknesses WHM has:

- NO RAID UTILITY WHATSOEVER
- Contradictive Lily System
- Job Abilities turned into Role Action fodder
- Extremely based on RNG for Lilies(except Cure II) and Freecure procs.
- Overshadowed heavily by D. AST's healing output
- Identity?

This is what I've taken for the most part from this thread.
