Anyone got potency numbers for ranged LB?

[Kiara1]

I had a guy get mad at me for wasting an LB on the golem boss in Qarn today, as a Machinist. While he was also a Machinist. He proceeded to piss and moan and call mr a noob

This remind me of when I was leveling my 2nd class. Arcanist. I was doing sastasha easy and at last bosss I used lb cause I aleays wanted to try mage lb.
The level 50 monk was furious "f*k u noob, uninstall we dont want your kind at level 50"
