I disagree with the closing of the question. It came off as ranty, but was asking for a objective answer of things to do. The user may have taken the objective answer and decided that none of the activities were worth his time, but that kind of subjectivity is okay. He never actually asked the answerers to decided for him what kind of activities he'd like. I also disagree with the argument that the author was already aware of all the possibilities... just because he knew some doesn't mean he knew all. And even if he knew all, it doesn't mean he knew that he knew everything. We shouldn't be closing a question based on what we think the author knows.
That said, your meta seems to really be about the editing of the question. Regardless of the reason for it, Wipqozn's edit improved the question by removing the unnecessary clutter of the author's opinion about the activities he was already aware of. I don't see how it fundamentally changed the question in the manner you describe. I don't even see the "Hellfire Ring" mentioned in the original question, so I'm especially confused by your assertion that it's original form was a duplicate of the question about crafting the Hellfire Ring.
