I'm wondering when the Weekly, Nightfall and Strikes are going to start dropping Radiant Materials. I get a good amount from the Crota's End Raid and I don't really need them but I do like to have an abudance of materials just in case I want to upgrade Armor or Guns that I just got leveled up and it would be nice to have more legendary weapons that require Radiant Energy and go up to a max attack of 331.
