Well the thing is, people are proud of their drops, especially with drops like Hopscotch Pilgrilm. The issue is that some people like me have very bad luck with perks. I have a Cryptic Dragon that has mulligan (which I kept since the other perks aren't bad at all). I had a Prudence that had mulligan and take a knee. I had a Zombie Apocalypse and Against All Odds drop that had Rodeo (ZA)/Persistance(AAO) and Grenadier. And the list goes on and on..... Re-forging helps out a lot because otherwise you would be grinding for guns trying to get the best possible perk roll for hours on end. Unfortunately, yes the drawback is that everyone has that roll but on the flip side the playing field evens out. Before HoW dropped, if you didn't have Felwinter's Lie or lucky enough to have another shotgun drop with Shot Package and Hammer Forged (or didn't see that the Vanguard was selling a great Secret Handshake), you would be out gunned since your shotgun wouldn't have the range to compete.

Yeah I just despise seeing lvl 23s with the best shotguns in the game.
