I have been trying to get Judgement of Kelgorath, and still don't have one pattern, even after playing the exotic mission. Today, Xur has it but patterns are not dropping. This is ridiculous. If you have the materials to buy the weapon, then you should get the patterns to drop. Period, end of story. It's bad enough Bungie is rolling back sunsetting, since I deleted all my sunset loot. Now I can't even get a weapon pattern for a weapon from buying it. Why are Final Shape sales down? GEE I WONDER!!!
