Why do people save LB till the end of the fight?

[Ryaz]

If I'm in a party that's doing poorly, I'll usually hold it until I feel it's safe for me to use the DPS one vs say a lvl 3 Healer LB. But if we're doing well, I'll use it as soon as it's safe so we can possibly get another level 1 or 2 one before the end of the fight.

Sadly, LB damage is like 1% of an Ex-Trial boss health, so most groups could probably safely ignore it and still be fine.

I often play casters/ranged so I never think about LB since a melee would user priority. When I do plan to use it I like to wait cause I want it to be my final move so I can gpose with it.
