A blue post earlier this evening announced that the beginnings of the pre-Cataclysm
events are currently being tested on the PTR.
Daeleht - Pre-Cataclysm World Event Thread
The early stages of the pre-Cataclysm events have begun on the PTR's.
If you're encountering any problems with the events themselves or have any feedback please post them in this thread.
The first of the pre-Cataclysm
events started earlier this month with Operation: Gnomeregan and Zalazane's Fall
, which are still available on live realms right now. We'll get you more information on what is happening on the PTR as soon as possible.
