Why won't you limit break?

I recently was told I LB too early in 4 man dungeons. I didn't know what I did wrong. I just LBd when the boss was about 40% health

You didn't do anything wrong. The earlier you use it (when it's good time in your rotation and it's safe to use it), the better.

Just FYI - in dungeons, 99% the time an LB is better spent on an AoE trash pull; cast by a Ranged DPS or Caster DPS. An LB on a boss doesn't do more than cut a few GCD cycles off the fight, which is unlikely to make any major difference or speed the fight up by more than a few seconds.

An Lb on a trash pack however can clean it up in no time at all; so waiting for the tank to make a huge pull then popping an AoE LB is the absolute best use of it.

This is correct!
