Nah, the JLB 47 on my Titan has a God roll. Javelin, Grenades & Horseshoes, and Hard Launch (I think that's the name of the perk.)
Got it from the Gunsmith a couple months back. It hit's like a truck; only Rocket I use that isn't Truth.
I don't see the point of the vacuum up heavy ammo perk. It's garbage, IMO
Also. Satire and sarcasm are two different things. I'm so tired of people putting a satire tag on a post and thinking it automatically becomes a [b]hilarious[/b] observation and parody of human nature/existence.
