Maybe they need to alter LB or make them personal. Tank almost never gets used, unless it has to, and it seems like the rest besides the healer lb in clutch situations can actually be a dps loss. Maybe since they changed it so every job has a unique lb3, that they could do different things, like party damage buff. It is apparent that using one is often risking your life as a melee in bad quick reaction situations. Though i have to agree, i rarely use them, and lately even as killing blow, hard to gauge how much hp it will do(almost always depressingly less than expected) usually the boss dies before it activates
