You've actually illustrated my point pretty well. Gjallarhorn is so much stronger than other rocket launchers that many people require it. Take it away, and... what? People start caring about other weapons that exist? No, that can't possibly be right. People having requirements to form a group is one thing. It's actually a pretty good way to find people you'll enjoy playing with. But a significant portion of the community being shut out of another significant portion of the community because they (the first group) all lack a specific weapon? That's another. That said, I think just straight-up nerfing G-horn was a lame way to handle the situation. They're already talking about new exotic quests in TTK, so why not just have a suitable acquisition quest for it?
