First of all, Cura II is a great spell when you know how to use it. Afflatus Misery is for use as a MELEE white mage (which is very fun ). Cura II is the single most MP efficient way to recover from an AoE move restoring up to 250 MP per person for 45 mp.

Second, you list Clear Mind V as a BLM thing that WHM does have, but WHM gets it at 80, which makes your list very misleading.

Third, 9 times out of 10 RDMs are too lazy to refresh WHMs (in my experience) so WHM/rdm works better for me than /SCH because I can refresh myself. plus when I convert I never cure myself, by the time I need to convert again I've Auto-Regen II'd all my MP back (gogo elvaan MP pool!)
