I have almost no weapon parts. A few things I've noticed, too: - I get twice as many blue armor drops than I do weapons. And when I do get a weapon engram, it's like a 50/50 chance it'll turn into a Mote or Strange coin. - On my main characters, I almost never seen Green engrams drop. It's like once you start hitting light level 280+, greens just cease to be in my drops. This also cut my ability to stockpile weapon parts down to nothing.
