The advantage to using it as a finisher is that no one suffers from the self-stun of LB's movement and uptime lock. With that lost uptime, it's no more efficient than your highest dps just continuing to do what they do, and may actually be worse than, say, the returned burst of a SAM, or a BLM finishing a fight with AF.

That said, if the team's AoE damage is less than 75% per target than its single-target damage, which it almost always is, it is at least better to finish an AoE pull with LB than to finish off a boss. Moreover, some healer GCDs of damage might be saved by using the LB early enough to overkill as few mobs as possible, more quickly removing whichever mobs were least lucky against crits and reducing tank damage taken.
