I don't think gjallahorn should itself be sold again, but would it be hard for Bungie to make an "exotic weapons engram"? And to make it different just like all exotics, because theft are so few of them compared to something else, to keep the "random class" aggravation alive, you and your friends buy it, you get thorn, another gets icebreaker, and the last gets a gally. Either rotate with armor engrams so that one or the other is there each week or put it along side. I've been chasing gally for a long time, but Xûr sells nothing of interest to me or my friends. The only exception to this when I bought red death recently. But my friends already had it and are now sitting on ridiculous amounts of strange coin
