Are you seriously KIDDING? I can't imagine who these people are who DON'T have thousands of weapon parts. What tha eff are you people doing with weapon parts? I upgrade EVERY legendary gun I get, if it has respectable perks. Why would you waste weapon parts to upgrade a weapon if it has crappy perks? You won't be using it so why waste the time and effort? If it doesn't have good perk rolls it gets used for infusion, or scrapped. I run my 3 characters thru raid every week, do my nightfalls, do my daily bounties, do some weekly Court of Oryx, and run a few heroic strikes weekly. How are you guys NOT turning in like 20 to 30 blue engrams PER DAY? How are you not then having a TON of blues dropping around 265-295? Each of those is worthless as an infusion tool, so it should be getting scrapped....for weapon parts. Seriously I have about 500 weapon parts on each of my 3 characters, and I've upgraded hundreds of legendary weapons all the way to max. How are you freaking people not overflowing with weapon parts? Tha hell is that even possible? I've upgraded so many guns since Taken King launched. Christ people go run court of oryx for half an hour and you should have 15 to 20 engrams to turn in, most of which will be unusable so will thus get scrapped for weapon parts and armor materials.
