was i wrong to use limit breaker?

My point is that in a dungeon, it's better to use the first LB as a caster on a trash pack than to save it for the boss fight in the middle. However, it's better to save it for the final boss for 2 bars melee, in most cases.

I like to use Ranged LB (And to see it used) just before a pull if pulling the boss will reduce it to zero. That extra 1-2% damage aint much but it's more than a wasted LB Gauge is worth. Casters can do the same thing as well since they can target from a distance.
