You know, people who say a class or job shouldn't be a cause it's not part of tradition...

There are 14 Final Fantasy games, not including the spin-offs.

If we don't include 6, cause anyone can really be anything in it. That's about 3 or 4 FF games that had class/jobs.

3~4/14 games that's less than half, that shouldn't dictate tradition.

Why can't there be a Chaotic Good Necromancer? Someone who is willing to do evil to do good? Oh look the warrior killed the only man that knew the certain information you needed to progress. Oh look now you have your friendly necromancer raise the guys soul temporarily to ask for information and he can't lie to the necromancer.

Yes Necromancy is frowned upon, but to become a sage among magic-users, you have to know all forms of magic.
