All three caster LBs need to reanimated at least so as not to be blinding to anyone in melee range. Red mage is by far the worst offender here, but all three of them do this.

Not sure if it's possible as well, but would be good for DPS limit breaks to all do a set potency of damage, but if for ranged and casters, if it hits multiple targets, that damage is equally split, making the limit break viable against a single target regardless of which DPS uses it.
