I didn't see you make a post like this when your level 10 pulse rifle was no longer effective against level 30 enemies. How come you weren't crying then? No matter how much you grind for that legendary, it is destined (no pun intended) to become obsolete once new higher level content is introduced into the game. Your Fatebringer was a god gun against level 34 enemies but do you realistically expect it to have the same punch against the tougher level 40 enemies? Guns, no matter how bad ass they are, become obsolete. It is a natural aspect of every and all RPG games. Hell, in Borderlands, you could find a bad ass gun and five minutes later, if you were lucky enough, find an even better gun that makes the first one obsolete.
