Is limit break not a thing?

[KisaiTenshi]

Not sure how often this pops up outside of 'Tales from the DF', but legitimate question: in your experiences, is DPS limit breaks not a thing in the Duty Finder? I've been running leveling over the last month while working on WAR, and I've noticed whenever a DPS gets asked to limit break, most of the time, they don't know how. It's been a while since I've done Hall of Novice and ARR MSQ, but was limit burst not a thing that was brought up at all?

Takes up space on the bar, and someone else will do it. Just like Esuna on healers.

With PotD I put the LB and the Auto-attack button on a bar that doesn't change between jobs. For the most part there is no need for the LB in any content, as the bosses are defeated too quickly that nobody remembers about it.
