Listen, Xur is a loophole in the RNG loot system designed by bungie to give you a guaranteed drop of the weapon you are wanting. It may be a different exotic every week, but if you run a character on Nightfall and end up getting 5 Strange Coins as opposed to a legendary or exotic weapon that you may spend 45 minutes to an hour trying to grind out for... it sux. Especially, if you get the shaft for a month straight. To put it into another perspective, I didn't get my first piece of VoG raid armor until my [b]12th[/b] time through, while other friends were getting full raid sets their 1st time. Xur was my only solice. I was absolutely stuck at level 29 for the longest. On top of all that, I kept getting the same weapons I already had over and over (not one exotic). The point is, do not depend on RNG for the weapons you want. You may end up waiting 3 or more months to get it. Xur is your friend sent to you from bungie. Enjoy your new IB bro.
