I know we all hate the shells but for newer players. These shells do have a neat perks and should be saved, here's why : They give glimmer for different enemies classes. There's Vex, Cabal, Fallen ghost shells and glimmer gives you heavy ammo syns. They also grab planetary materials, so you don't have to buy or collect them. Also, the endless Raid shells you get will infuse these nightfall ghost shells, so dismantle with caution, guardians.
