was i wrong to use limit breaker?

Appropriate LB is appropriate. If multiple enemies then caster, if single target then melee. Melee usually gets priority but it depends on the situation.

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.
