When you look at the history of Xur and everyone wanting the coveted Gjallarhorn: Xur has only sold Gjallarhorn once; September 19-21, 2014. The second week of his weekly appearances. Looking at another exotic players desire, Ice Beaker: Xur has sold it three times; October 10-12, January 16-18, and just this previous week. A good yet less desired exotic he sold, Plan C: Xur again has sold it three times; November 28-30, December 5-7, and February 6-7. Now, down to the big rant on the worst rated and reviewed exotic to be in the game of Destiny, No Land Beyond: Xur has again sold it three times. I will make a duly note that he had sold it the three times within 90 days! Let's look further. Since the first No Land Beyond was sold by Xur, 9 weeks have past. Within those 9 weeks only 5 different exotics have been sold, with their respective number of times sold . No Land Beyond(3), Ice Breaker(2), Dragons Breath(2), Plan C(1), and The Last Word(1)...... What has happened to the 9 other exotics weapons in the past 9 weeks? Is Bungie attempting to tell us something about having No Land Beyond for future use? 9 weeks have past and one-third of the exotics offered are No Land Beyond....the probability of No Land Beyond being selected for Xur to sell is one in fourteen ! That's 7%! I took into account of the weapons he will not sell(exotic bounties, monte carlo, hard light, hawkmoon) What's the future of Destiny if there's no diversity? Is selection of exotic wares fair? Is Gjallarhorn forbidden from returning to Xur's weekly inventory? What about Thunderlord being offered?
Thought this was somewhat applicable to your topic. Here's the list of every exotic he's sold and the week # he sold it - sorted by weapon name. Maybe it's just me, but the first potential pattern I saw is that he's moving towards 3 of each weapon below. Could be wrong, clearly, but nonetheless it's the first thing I noticed after sorting the list this way. The only weapons he hasn't sold at least twice is the MIDA and Gjallarhorn. Would be interesting if one of those two popped up next week.
