@wakdestoyer took the secret 4th option, so I'll take the secret 5th option: Be sad because now that everybody has a Gjallarhorn, everything in the game will become a joke, it will become imbalanced, and it own't be fun any more. Disclaimer: I have been saying this ever since the idea of Xur reselling Gjallarhorn popped up. And I only just got my Gjallarhorn last week. Even without a Gjallarhorn, I would still say 'no' to Xur selling Gjallarhorn. (but luckily I do, at least. Thanks nightfall, lmao)
