I hear you, it's still not enough. It might be down the road but with do many weapons and so many things to use the parts for you run out of them fairly quick. I had like 800 or so parts, I was like well I don't need them, I used half for the rank up, and then the rest for weapons, now I'm in a slight shortage (2/3 of my characters don't have many). I do nothing but collect blue engrams, and still it's a pain. I'm sure once all the weapons are out we won't need that many , but right now the draught is real!
