So how would this buddy feel if the day after he landed a Ghorn on his 101 crota completion...only to see Xur was selling it to everyone the next day? RNG is not luck, it's a numbers game. Keep grinding until you earn what you want most...even if it takes a long time. Several guns I've wanted took hundreds of hours to land but that's part of the game. You have to keep grinding. Also, my point is that only specific guns should not be sold, not all of them. Thunderlord is definitely in the shouldn't sell catagory.
