as a melee dps i see what you are saying. i do enjoy a challenge. and for certain bosses it is completely just a timesaver. But i will say that correctly timed limit breaks can actually move a boss onto the next phase of its attacks completely skipping the previous phase. Take Psychflayer or whatever the first boss is called in AK, if you lb him at around 40% hp he will skip summoning a golem allowing you to dps that boss a little quicker. I agree i like a challenge as well. But the lb i feel i only HAVE to use on certain bosses at certain times. Yes i have beaten almost every boss without the use of LB because other people died/didnt know to use it. So it really is just a timesaver.
