I haven't made any assumption about a prejudice against warlocks. I understand your reasoning that it would be a waste of man power to select old wares, but this is as assumption based on our limited, external knowledge. That said, the old wares do [i][b]support[/b][/i] the assumption that it isn't manually selected. They don't, however, prove it; especially considering remarks that I've myself witnessed Deej make about a guy in the office that he talks to for information regarding Xur's upcoming stock. While this also doesn't prove anything, this does support the assumption that it could be manually selected. We're left then with only two facts and equally valid assumptions: There is a history of Xur stock predating the game's official release. There is an individual at Bungie with foreknowledge of Xur's stock.
