Why won't you limit break?

To be honest, sometimes I forget, but I try to LB at 15-25% if I do remember.

Also, the most efficient way of using LB is on a huge trash pack, not the melee DPS using it, but that depends on the tank.

Here is the thing. In the current dungeons, there are no huge trash pulls with 4 or more groups. Maybe Kugane castle, but those come in waves.
