Why do you save your LB?

[Lafier]

If you have 3 dead members in Titan, your LB will do so little damage, you might as well not use it and eat a landslide/weight out of carelessness.

Attack LB is the combine raw stats of all members of the PT. with 3 dps dead, you LB is basically crappier then regular skills.

Correct me if I'm wrong, but isn't the LB based on the ilv of the weapons of everyone in the group? I thought I seen a post on Reddit about a group that tested the LB with full gear on, and then naked with only weapons, and with low level weapons. It has been awhile but I'm pretty sure LB really doesn't change if someone is dead does it?
