Hortus has posted a sticky about the current PTR issues which addresses a lot of problems in and questions about 2.2. Most notably, he has confirmed that Zul'Aman and Guild Banks will not be in patch 2.2. He also has confirmed that Voice Chat will still be in 2.2, but it is not yet available for testing on the test server.
In addition, Hortus addressed some of the problems people are having with premade character copies. Hortus says that if you get an error when trying to copy a premade, the queue is full and to try again later. He does not address why the error message doesn't just say that...
Also, it seems that even though some premade characters are missing abilities or have abilities they are not supposed to have, they do not intend to fix them at this time.
Side note not mentioned by Horus: Copying characters that are not premade to the test realms is also on a several day wait.
Hortus denies that the Orc Shoulders are now bigger than before the bug:
Orc shoulders are now the correct size, they are not any larger than they were before, it's your imagination.
He also addresses Athlon errors, authentication issues and how not to get your post deleted.
It seems that with all of these issues and Voice Chat not even being tested yet, Patch 2.2 is a long way off. What are you most looking forward to or dreading in 2.2? Have you successfully copied a premade? If so, any problems and how long did it take?
