The real issue will present itself in the 264 numbers. Based on the 251 numbers the 264 look to be very similar to the Badge items. In which case people who bought the Gloves/Chest and passed on 264 tokens got screwed, cause they could have gotten a free set bonus outta the deal and an item they can upgrade with just another token.
The lack of defense could present and issue. They are probably trying to remove it slowly as they can due to it being removed entirely in Cata.
