Why do you save your LB?

[Bluevann]

Dungeon wise. It is unwise to push bosses in and out of certain phases too fast. That's a "derp" moment when you push a phase without preparing for it, due to bursting issues.

I am talking more about taking out adds (like in the Haukke manor case) or finishing the boss quickly when the "final nasty stage" comes out, such as in Dzmael. I'm a BLM main, and I was always told to do that in both cases.
