The community agrees that Izanagi's Burden is part of the optimal loadout for GoS. I, and I imagine many others, are having a hard time getting into a raid group because I don't have the best loadout, making it particularly annoying that part of that loadout is completely unattainable!! Bungie please make this a priority and fix the quest by next reset, if it was literally any other exotic quest it wouldn't be as pressing. Just make it so the keys can be forged by any of the 4 forges since they're on rotation now and fix the bugged portion where one of them can't be forged at all.
