Why won't you limit break?

I'm so used to internally raging about the lack of LB as a healer that whenever I play DPS I use that thing every time I can. It seems to be a law of the game that the person most suited to using it never notices it's there.

There's usually another melee DPS or I'm playing as Bard.

People who are new might not use it unless they are told for fear of being yelled at.
I can't say for highers levels but it doesn't seem to matter that much unless you are doing harder trials.
