I do the treasure room glitch. I don't have a problem with friends who play together, find a legendary they all want, and then dupe it for each of them. My problem with duping is it leads to people believing they're entitled to every rare in the game with no work, and then they come begging on this board. The treasure room glitch still requires work, and it's fun to do.
I'm also pretty convinced Gearbox put this glitch in on purpose, otherwise completing the challenge for opening Pirate Chests would take forever.
