The Rawr simulator, which includes modules for DK DPS and Tanks has been updated again for 3.2, with most of the content now up-to-date.

We’ve also had Ulduar bosses on scheduled tests, and… they were beaten. So in one evening or less, the bosses died.

As an outcome, World of Raids now have an Ulduar guide including loot and abilitites which is great content.
This is the new raid Blizzard had hoped would be challenging. Certainly, boss tuning is not completed – that is the point of testing in the first place – but it does raise questions. From launch in November until now we’ve …
