The double rewards are great but the balance between Palindrome, Shadow Price and Swarm drops is really skewed. I've been running nfo's from Hero level to GM for days and only gotten 1 Palindrome in GM and 1 at Hero level both with not so good rolls. I have deleted almost two dozen Swarms and Shadow Price. Presently the most sought after hand cannon in the game and you have to make it so hard to get. Update- ran GM's all last night and most of today and finally got 3 pali's to drop. Do they have the rolls that everyone is looking for? No. Bungie consider this- Allow us to build a weapon blueprint and charge us for it. The more perks you lock down the more resources you pay. Barrel choice could cost enhancement cores and glimmer. Weapon perks could cost prisms and ascendant shards. I know your first inclination is to think we would stop grinding GM's. Actually the opposite would be true. Let's say the total cost of blueprinted weapon would be 5 ascendant shards, 20 enhancement cores and 15 prisms. Once a weapon is obtained using this system the player would be back to grinding to restock resources. On top of that we could do a pve build and a pvp build which doubles the resources needed to be earned. Bungie there is so much frustration in the current rng system, just think about it please.
