Sorcerer and Witch has the same 3d model?

Is it me or they are identical? Why?

They should at least change hair colour or something maybe its placeholder?

I imagine the skeleton will remain the same for either variation of the archetype to try to save on animation budget. Its probably the reason why the Warrior was a Karui foundling, so they can get away with their big Karui body style on him (although why they didn't just make him an unusually large guy I don't know).
