Move on dude. Fatebringer has been the PvE king for a long while. Its time to try something new. Besides, most people aren't gonna dismantle it anyway. Time to give another weapon(s) the spotlight. Besides, bungie has more info about old gear and weapons after gamescom so hold on to freakin britches for cryin out loud. Destiny is an mmo. Once year 10 rolls around, you'll have memories many others won't or didn't get the chance to enjoy to the fullest. You'll look back and be like "oh I remember when me and my friends did vault of glass when it first came out" or "I remember when fatebringer was king" and all that stuff. Your grind wasn't a waste.
