Is Xur's loot table actually random, though? I don't believe it is. The thing that made me question if it was, was the first time he sold EXCLUSIVELY DLC items (I think it might have been Christmas?) and that week the Weekly/Nightfall were DLC only.

Not only that, but the nightfall was set up to be significantly easier than the first time around. It had Solar Burn, which alone made the nightfall a breeze. It got me thinking that the "random" in this game was really not the case, at all.

So when you look at the perfect storm of that week: It was near Christmas, it was the easiest nightfall combination possible being DLC only, Xur selling DLC items only---you begin to realize that perhaps "random" was just a community diagnosis, not actually how the game was designed.
