Why are ranged using LB so much now?

[Lexia]

(Chrysalis, as an example. Or Haukke Manor (hard) pre ilvl 110)

after i110 when everyone is overgeared the LB doesn't even need to be used on the tear but I see so many parties when get it in roulette still think that the only way to kill the tear is to LB it. I would say most people either 1: don't care or 2: don't know the strength of the LB/their own party.
