For those of you who use Authenticators, there is now an extra blank on the main login screen for your six digit code. If you forget to put the code in, it will prompt you in the same way it currently does.
The ability to manage stacks of items a little better has been added to the Auction House. Here is a quick look at that feature.
The Maximum button updates the information to the maximum you have available for that item. Being as I only had 12 pieces of Frostweave on the PTR, it hit a max of 12 instead of the normal 20 per stack.
Here is a look at the Random Battleground finder. It's much like the Random Dungeon Finder we have currently with a relatively simple interface.
Here's the call to arms information for this week's battleground. It has the same extra rewards as the random battleground.
If you just select a non-Call to Arms battleground, you get a brief description of the battleground. Nothing special here, just noting the differences.
In the Dungeon Finder, there is a new option available. This one allows you to find groups for the holiday bosses. According to the information from Blizzard, this will end up being the only way to access these special holiday bosses. We'll know more details further into the PTR process.
Here's a look at the 'quest' rewards for getting a group to do a holiday boss. As you can see, the interface still needs a bit of work, but expect to be using something like this for your Headless Horseman tries (or your attempts at melting the Ice Stone).
This is a new Dalaran vendor located between the engineering hall and the mining hall in the professions area. He wants your Frozen Orbs and will trade you other goods for them.
Here are some of the items you can nab for your Frozen Orbs. By the way, I expect the Frost Lotus price to be a mistake. Expect it to cost a Frozen Orb by the time it goes live.
