Some of the FE class names completely miss the mark to begin with. Such as the Myrmidon. In Greek myth, where they come from, they armoured up like any other warrior on the battlefield. If anything, they closer resembled FE mercenaries, as they were known for their skill.
No reason why content developers shouldn’t be allowed to rename classes to fit their setting†/ideals/etc.
.
†Fates did it. And everyone loved those games.
