We need to be able to buy weapon parts and guardian materials. Reforging is now a regular thing and weapon parts are running low. Since it's rng based you can get god tier rolls in a few or after 50 plus rolls. We need to be able to buy weapon parts. Guardian materials need to be available as well. When you have 3 characters you can't continue to play and have enough materials for all 3 at once. You have to pick and choose who gets what blue engrams for that extra 2 mats. If you're really desperate, you'll buy greens from the vanguard, equip them then cash in bounties to level them up one by one, which isn't a quick process, then dismantle them. It's not a fun thing to do. Please allow us to purchase guardian materials and weapon parts.
