Hey Bungie! I have multiple items of legendary (even exotic) armor and weapons, but the only materials ever required for upgrading is the relic iron. What is up with that? I understand using iron for armor, but what is the purpose of collecting spinmetal, helium filaments, and spirit blooms if they are never used for upgrades on armor and weapons? I really hope something is done, otherwise, all the time and effort you put into making the odd little materials would have been wasted. Thanks for taking the time to read this, see in the Tower.
