Xur should sell Izanagi's burned tomorrow. After having waited three weeks to get my key blueprint and having used the key only to find the quest is still bugged, I am admittedly annoyed. How dysfunctional this quest is has become simply atrocious. I imagine many people (myself included), have used the key to no avail only to feel cheated and dejected. Sure, you can blame that on ignorance. However, after having been told by Bungie that the quest was fixed I believe it's hardly our faults. A simple solution would be for Xur to offer the exotic this weekend. This would assuage the irritation many players have developed in relation to this quest.
