I willingly admit that I consider myself a casual player in this game. I have one toon and that is all I have time for. I am ok with the drop rates of everything else EXCEPT for weapon parts. I think this was a ridiculous move on Bungie's part, especially when you consider that, at least for me, my drop rate for armor engrams vs. weapon engrams is seriously like 7:1. Even with a single toon and limited play time, I am perfectly ok with strange coin and mote collection rates. Weapon parts drop rate compared to usage is so out of balance when you compare it to armor mats vs. usage. This needs to be fixed Bungie. This is the only thing in the game I have serious issue with right now. Different ways to fix this: 1. Remove weapon parts from infusion. 2. Remove weapon and armor parts from rep gain and allow the gunsmith/class vanguard to sell them for glimmer. 3. Balance the drop rate of weapon engrams compared to armor engrams. 4 Roll back the decreased drop rate on dismantle.
