3.3 and BoA Cross Faction

Q u o t e:

On the EU a Blue said that in 3.3 we will be able to mail our BoAs to the opposite faction.

It is important to note that not everything that is introduced on the Test Realm or in the Test Realm Patch notes will make it to live. When these changes were announced it was intended to release them for 3.3, it is a bit early to tell if they will or will not make it though.

Q u o t e:
However, is it restricted to the realm your character is on? The name "Bind to Account" is a bit misleading if this is the case.

I am sorry for what confusion this may have caused, though we try to provide as much information as possible tooltips can only hold so much information. For this reason we provided several support articles which are accessible both in-game through our In-Game Knowledge Base and through our Support site.
