hi so i was doing ifrit and titan hard modes first time for my main story quest. During the HM battle with primals i use limit break whenever i can. A few people chided me for using limit break and called me a noob. However, those people did not explained what was wrong with me using limit break.

I talked to a few people on my fl about it and they said i should use it and the people that chided me were idiots. But i am sure there was a reason why. Later i googled and apparently something i read says that limit break will do more damage if i used it until 3 bars. Is that the reason? or am i missing something?
