Necromancer in Heroes' Gauntlet may work differently. Like, as a medium who asks the dead for aid. Or she is a WoL who has lost her beloved people and grief to the point she studies dark art, but her heart is still of a justice holder, unlike Edda who has gone too deep into the rabbit hole. Similar to Thief being considered evil for WoL in the Source, but in another shard, a thief is akin to Robin Hood, so it is regarded as a hero class to local people.
If FF14 ever adds an undead-user class, I think the name would change. Like Spiritualist. I like talk to the dead and help them rest, like Yuna who helps the Unsent.
