I'm pretty enthusiastic about these changes. MRD/WAR looks like a decent setup, with that AoE Stun ability looking like it should be a lot of (potentially suicidal) fun.

I noted earlier someone commented on the loss of Shell - didn't they remove Magical Defence anyway? I thought they upped Magic Evasion and resistances instead? So that probably covers Shell off.
I'm actually replaying FF3 at the moment and when I saw CNJ/WHM getting Aero, I was pretty happy with the route they had taken.
