Idiocy

[Leonlionheart]

Celerity only is worth it for casting Raise/Reraise anyway.

The time it takes to use the job ability and casting the spell doesn't help at all. Unless it is a super long spell and recast time (hint: Raise).

Recast -50% says hi...

Stun every 17 seconds, you can have this

Edit: In terms of WHM, though, it's true that it's not of much use other than raise/reraise.
