Agreed, across 3 characters I now have about 60 weapon parts. Bungie, if you want to keep people from grinding rep with weapon parts, REMOVE the weapon parts option for grinding rep. Don't nerf the upgrading of guns, arguably a core tenant of the game. It makes no sense, unless everyone is correct and this is just setting us up to have Tess sell us parts for real cash. That would be a path to a place you don't want to go. I cannot speak for everyone, but I think that would be something that would get me to leave Destiny (game I play a lot) to go do something else worthwhile.
