Perhaps this is just me not understanding the mechanics fully however it seems I am still unable to send items between characters on the same account although after extensive reading of the update list the items I am unable to send are NOT on the list of items we're still not allowed to send, thus meaning the items should be sendable.
For any mods reading this the items in question are the rare/ex statues eg: Odin, Alexander, Shadow Lord, etc.
These items are not on the given list and therefore, in my understanding, should be deliverable between characters in the same account.
