i did a bit of limit break damage testing.

This info isn't going to stop every brd / mch from spamming it as soon as the bar is full.

I'm going to assume you're only talking about at the final boss? It's stupid when people expect me to let the LB sit there full for 60% of the run when it can be used to speed up the clear, or when they get mad at me for using it on a pull with 6 mobs right before the boss because "we need it for Lady Amadine."
