There is currently a curious bug in WoW that might bring a lot of gold to some players. The Legendary Tokens are tradable!
The latest patch of World of Warcraft is live. Update 7.3.2 has brought few changes, such as additional game data for the raid Antorus, the Burning Throne. Additionally, there were some changes to the Legendary system. If a player already has all legendary items with their character, they can still receive additional legendary items.
While there are no duplicate items, there are “Tokens” for another class. These are bound to the account and can then be sent to characters of the corresponding class. At least, that’s the official plan.
Tradable Legendaries in Raids and Groups
However, it seems a bug has crept into the patch. If such a Token is dropped by a boss during a raid or dungeon, the same exchange rules apply to this Token as for regular loot.

In plain terms: The legendary Tokens can be passed to other players in the same raid group for up to 2 hours!
This at least opens the door to trading legendary items, although it is of course difficult to plan when such an item will actually drop.
Whether this is truly a bug or intended to help other players in the raid guild is still unanswered. Since the items were meant to be bound only to the account, we assume this is a bug in the game.
Presumably, the problem will be fixed in a few hours with a hotfix.
