I opened up my game yesterday and a guy joined, stood in front of me, and dropped a conference call. He stayed for a while then left. I'd wager that it's dupped.
This gun is ridiculously powerful. Providing ammo supplies hold up I can walk through any area and kill multiple people with near no effort.
It makes the game way too easy. So much so, that I kind of wish that I hadn't picked it up in the first place. I try not to rely on it, and instead I like to use my other guns, but I find some mobs have a tendency to kill me very quickly. So I end up using it, falling into a vicious circle.
I am playing on True Vault Hunter mode.
