Refusal to LB3

[Thunda_Cat_SMASH]

Isn't DPS lb only based on the user iLV?
I thought with equal gear, all melee, range and castee do the same damage respectively to their DPS category.

It's based on the weapon level of the party. Counter intuitively, if the melee is a MNK/DRG, a caster or ranged using the LB3 is generally a dps gain, especially in the case of a MNK. Failing that, the weakest melee dps that is neither a MNK/DRG should use it.
