I'm saying I'm in no danger of losing weapon parts. My play is a mix of patrol, strikes, and crucible. I love to stock up on bounties. All these things give me plenty of green and blue weapons/armor, be they from chests, engrams, or post-game rewards. And I work the gunsmith and align with a faction, so those packages net me even more materials. But here's maybe the kicker: I am always leveling up a weapon or armor, when I can. If my legendary/exotic gear is maxed out and I have nothing but blues or greens on hand, then I equip them, cash in some bounties, and discard for even more parts/glimmer. If they're legendary I'll even get more marks. Truthfully, I don't see myself falling short on any materials. Maybe I'm in the sweet spot Bungie is looking for? Not casual but not hard core? No clue.
