I really wish Gauss Barrel and Wanderer's Minuet changed the character's stance. It makes the character have a cast time, so make them look like they're focusing more [make the Machinist aim down his sights or something and the Bard just aim directly at the enemy as they cast].

Also for Bard and Machinist, make them move a bit more whenever they do....well anything. Since only their upper bodies move, it looks unrealistic and bad when you realize their legs are perfectly still yet their upper bodies and arms are flailing around.
