Another option to consider is spell damage caps and scaling. A RDM's spells are obviously going to be weaker than a BLM's version of the same spells. I'm iffy on recasts and mana costs because I'm not too keen on dead periods, which are expected of a dedicated caster but not from someone in the front lines. Going OOM due to carelessness is different from going OOM by design, after all.
