If you have earned your Exotic Swords(or just the Dark Drinker in my case) you will see them in the Exotic Blueprint Kiosk along with the Truth and Thunderlord, but what you do not see is a slot for anymore heavy weapon blueprints that have otherwise not yet been discovered. Now it is no surprise that Game Informer is not at all accurate as they pertain to Destiny. Clearly shown by their article on the "coming soon" all new Loremaster class sometime last year or early 2015. Could the Sleeper Simulant actually be just a BS scavenger hunt that never ends?
