Why are ranged using LB so much now?

[AlphaFox]

Two major times tank LB was great ->

1.World of Darkness when the raid derps and lets the boss get too many stacks of clouds.
2.T13 Teraflare

Okay so as I said, never did past Turn 5 so unless Teraflare its required, that only makes one as WoD is an ID 10 T error and not 100% mandatory
