Give players the option to dismantle Prime Engrams and receive 5 cores per. Once max lvl that’s when you want to start MWing your gear and creating gun or ability centric builds. At max lvl pulling the slot machine by cashing in a Prime Engram for a good weapon or armour isn’t as impactful. Dismantling said engram and getting enough cores to fully MW a piece of armour is worthwhile. Little things like this Bungie will improve the player experience. Write the code already.
