Why do you elitists keep posting about this. Move on. Why do you care how others obtain gear? I've yet to complete the raid on normal but still have been and gathered gear. Ive gotten Nightfall exotics and even a few from lucky engrams. Guess what? I didn't earn those. I got lucky with RNG. Quick go check the definition. Some people are unlucky so they save their coins and purchase the wares that Xur sales. It doesn't effect your game or experience in any way whatsoever. Get over yourself.
