Yeah, I guess so, hehe.

Necromancy to me is first and foremost the manipulation of the forces of life and death; Manipulating living and dead things, not creating them from thin air. An ideal necromancer to me should be able to find the bones of a giant in the field and make use of it to lift a fallen rock blocking the way, but not call in a skeletal giant in the middle of a populated city. The latter encroaches too much on the summoner's thing.

Re: Blue Mage, I actually meant more the final fantasy blue mages, who piece together their spell list by defeating monsters and learning their moves rather than by a singular theme.
