Move Existing Themes Forward

If you made some achievement you will be awarded a title. The Exalted worked differently as the team wanted to move the title to a different achievement altogether. In this case, if you have the achievement you’ll keep the title. If you’re close to getting the achievement, you might want to hurry and get it before 4.1 because after 4.1 you’d need to also gain the additional rep to meet the requirements, earn the achievement, and get the title. There is much latest content in Cataclysm. There’s also a plethora of updated content to advance the story.
Similarly, there’s plenty of new content still to come in this expansion. However, the team will keep moving existing themes forward when the story calls for it. There were specific reasons for originally entering Zul’Gurub and Zul’Aman, but those reasons by no means wrap up the story of the ancient troll empire. These city ruins still are considered as a major purpose in troll lore, beyond just offering new locations to get loot.
