Holy crap, I forgot AF3+2 pants. That would vastly change the HP:MP ratios for all WHM spells, meaning BLU doesn't even come close to touching them. What the hell, Saevel?

I think the issue that people are forgetting with BLU, though, is the fact that they can only set so many spells at one time and there is a delay after any sort of changes wherein the BLU can't cast anything at all. People seem to underestimate the value of this time. Arts are the single biggest reason that SCH is such a shitty mage, and even those are more lenient than BLU spell setting. BLU loses a ton of versatility by having to set their spells for a given role and then be stuck in them, unable to change their role instantly on-the-fly if they need to.

As a backup healer, they have decent spells, but if they're set as a backup healer then they are only a backup healer unless they want to be useless for a full minute while resetting spells. They can't handle backup healing while doing crowd control, enfeebling, and contributing worthwhile nuke damage. That doesn't happen. Who can do that? Red Mage.
