As I mentioned in this thread, the information contained within the ticket linked in this thread was factually incorrect. In the current Friends and Family Beta build of Reaper of Souls, a number of items including gold, Legendaries, and some gems and crafting materials are BoA. We’re still in the process of testing out how this impacts the game as a whole, so that these changes are not final, and may be subject to change as the game evolves.
The Beta as it stands is a work in progress, and when we have more finalized information for you concerning what items are and are not planned to be BoA, we'll certainly let you know. In the meantime, thanks again for your continued feedback on the subject! :)
