Why do you save your LB?

[Alkimi]

Go test it, any melee will realize their LB is worthless crap with enough people dead.

Melee LB is based off the average weapon damage of all the melee dps (DRGs and MNKs) in the party. Whether or not there's people dead is irrelevant, it will always do the same damage.

Caster LB is the same but average weapon magic damage of your caster classes in the party. This does not include healers.

Glad I could clear that up for you.
