Mailing BOA Across Realms?

At this time, Narts, Bind on Account items are able to mailed to all characters, including cross-faction, on a single realm. I'm afraid the only way to transfer these items to a new realm would be to move the items to a character, and then transfer that character to a new realm.

While our developers may be looking into possibilities of expanding the Bind on Account restriction in the future, there is no current news I could pass on for the time being. The General forums would be a better place to watch for that kind of news, and if there is a particular functionality you would like to see, we highly encourage discussion in our Suggestion forums! Our developers actively read those threads, and they are most eager to hear your thoughts. =)
