It's such a good idea that Age of Wulin made over $20,000 at a virtual auction before it even existed, at which point the term "good idea" is destroyed more tragically and expensively than spontaneous combustion in a bank vault. Because 16,000 of those dollars were spent on the Dragon Slaying Sabre and Scabbard.

The blade was expensive because it would be the only one in the game. The game that no one had played yet. Spending $16,000 on an item in an unreleased game is like buying your unborn child a human-leather masturbation glove: crazy, premature, and making all kinds of terrible assumptions for a self-involved waste of money. And that would still be a better purchase, because the glove won't disappear when (not if) the developers switch off the servers.
Legendary blades are a huge part of wuxia novels, usually as swords so sharp, they stabbed the deus ex machina to take its place, but buying one is how you become the bad guy. If this were a real wuxia story, everyone else's first and only quest would be "defeat the fool who gilds the grip of a warrior's blade." For that much money, the sword had better be Excalibur, complete with a lake and genuine mermaid to hold it. And even if it taught real sword fighting, it wouldn't be worth it because we have guns now.
