The first impression I had of the beta was "WOW" – why? Because they really changed a few things on the User Interface. I copied over my shaman – with a bit of gold – as premades aren't available yet. There was so much to explore – it was hard to decide where to start. Upon logging in – I naturally got the "Your talent points have been reset" message. This found me hitting the P button.. and WOW, what a difference.
Check it out- you couldn't visit the profession trainers, and you couldn't find the archeology trainer yet – but hey it's new yet.
The next awesome find was the talent tree itself. It resembles the Add On Talented – so if you're used to that type of interface, you'll find yourself right at home with the new talent point UI.
I'll add a post on once you spend your talents - the top changes but I've got to download the updated version.
