The Burning crusade saw a lot of changes. The Nazgul left the server in search of more hardcore raiding. Ordo Malleus and the The Black Sheep merged and Blizzard changed the raid sizes, reducing them from 40- and 20-man to 25- and 10-man respectively.
Now raiding alone The Black Sheep finished all the 10-man raiding content this expansion; Karazhan and Zul'Aman.
See, I got better!
Towards the end of the expansion the Nazgul returned to the server and suggested we reform the old raid alliance. Which this time lasted a grand total of zero raids. They felt that it was better to take random puggers rather than Sheep, to a Gruul's Lair raid, due to people 'not having good enough gear'. This led to The Black Sheep holding their first and only 25-man raid, during which we 1-shot Gruul.
The Nazgul left the server.
This started a series of raids with our friends at Bloody Pact, to see some of the 25-man content. A highlight of which was clearing Magtheridon's Lair...
