Ok, we're getting close to the point where we will need testing of Ulduar boss encounters on PTR, so let's talk about Ulduar testing!

We're going to be performing testing differently than in the past. We're looking for much more targeted feedback, and we don't want to just have the zone freely open and allow extended, unsupervised testing to take place. So, when the PTR servers come up with 3.1.0, by default Ulduar will be turned completely off. We'll instead enable Ulduar and specific bosses during times where the encounter team can observe testing.

Shortly after 3.1.0 PTR is up and running, I'll post a schedule that will indicate when we will open specific bosses to testing. We'll have testing opportunities for both EU and NA region PTRs in their respective prime time playing hours. There might also be a boss or two we do leave up for extended testing, and some bosses will only be tested in either the EU or NA. Some encounters won't be up on the PTR at all! There's 14 boss encounters in Ulduar, there will be lots to test. The schedule will be quite flexible, check in the Dungeons & Raids forum and on the PTR forum for updates.

The first set of boss encounters to get testing will include:

* Freya
* Thorim
* Hodir
* The Iron Council

Both 10 player and 25 player versions of the encounters will be open to testing, and we expect players to have nearly full Naxxramas gear. While Jillian McWeaksauce might make appearances on the PTR to provide testing consumables, please try to bring your own.

I hope to see raid groups of many different skill levels on the 3.1.0 PTR servers when they become available!

Additional info on first boss
The first boss has you enter 1 of 3 different vehicles (Chopper, Demolisher, and Siege Engine) to fight your way through an immense Iron army to the Flame Leviathan and defeat him. After that, there's very little use of vehicles by players. We'll have the fight up on the PTR at a later date, but this fight isn't in the first wave of boss encounters to be tested.
