I like how most people don't give a fuck about Xur selling the exotics anymore but for heavy ammo synth lol
That's one of my main gripes with Destiny. Compare this to say Diablo where you still to this day might not have even seen all the Unique items it has to offer. In Destiny, most active players have their vaults and mule-characters stocked with exotic items and the total amount of exotic weapons in Destiny is 22.
Even Diablo 1 had 56 unique weapons
Xur should have some suprises in store, there should be stories and internet legends of people who have seen some new weapons that there are no details or specs online yet.
Now we just wait for that random Ballerhorn drop for those who still don't have it as it is single handedly the best bazooka in the game :/ As for other variety, Ice Breaker and Suros Regime should have some competition in that department too.
