Blizzard released a new WoW Alpha build January 15'th. The build codename 3419 is now beeing played by the alpha family testers. The last one was testing of UD and before that humans and orcs to my knowing.
That leaves out NightElves. Another reason to tell people that we REALLY need the packet dumps very very very much so please come to irc.wowforge.net in channel #wowforge and help us!
Give us the packets if you can or give us the new build and we will look into it for more options to exploit and make a better server with it.
