Caster vs Ranged LB

What's the damage difference, if any?

I would assume the ranged LB does more than the caster, but less than the melee. I've been able to find the new names, but not their potency yet.

Idk about LB3 but i was doing a dungeon with some friends, our bard LB1 did 9.8k while mine (BLM) did 11.3k

Don't know the potency on ranged. I'm just happy there's a fight where I get to use my LB3.
