At one point, a Treasure Card Vault existed in a Test Realm that I would love to see be brought back. I assume that one reason the Vault wasn't brought to Live was to prevent people from Trading certain Treasure Cards to lower level characters that weren't supposed to have them yet. Wouldn't it make sense to just simply slap a No Trade symbol on it like what you did for the Jewel and Gear Vaults? It'd be nice to store more Treasure Cards on a Single Character.
