why during cutscene its always like this ... (small spoiler)

[Critical-Limit]

It would just be 12; the game engine would handle the differences in jobs, races, and equipment.

Disagree someone made a mighty fine point about character height. A swing to cut a tall person in half, lalafell can just stand still and it'll go over head. So you would have to some extent make the enemy NPC's swing either always vertically. Or have to animate a different height swing. So races would play a role in animating fight scenes
