and what is better to do in a boss fight (assuming there aren't too many adds in that fight and that one LB bar is full before initiating the fight):
use it right at the beginning? i noticed a LB doesn't add any aggro
and if it's a fight where you can have more than one bar: wait until more bars are full? or always use it with one bar?

and do damage buffs increase the damage of a limit break? so as a pugilist/monk, should i get all my buffs up before using the LB? what about debuffs on the boss like +x% blunt damage? if so, what kind of damage is a melee dps limit break? and can a limit break crit (which would mean i'd best activate internal release before using the LB)?
