I think the issue is that too many of you, upgrade and keep too many weapons. Other than the class specific guns, you only really need 1 set of weapons to move between your guardians. Sometimes I will test out a new weapon, to see if I like the base functionality of it, the base handling, and the feel of it, but most of the time if it isn't in the 294 and up range, it's instant weapon parts. Alot of the drops have perks I have no interest in so unless its high 290's, for infusion, they are just weapon parts. I have 2 guardians in the 295 to 299 range and my main at 302. But since I move my main guns between them all, I dismantle tons of guns after running strikes, court of Oryx, and dailies. And then the ton of blue weapons that you get in patrol and crucible. For every gun I choose to keep and upgrade, I bet I dismantle 10 to 20 a day. So even at only 2 a piece that's 40 parts a day. And personally I have never been under 100 parts per guardian. I should add I suppose, that I didn't go reforging crazy in HoW, so as a day 1 player I have plenty.
