World of Warcraft: Cataclysm Post-mortem Q&A

Blizzard's official World of Warcraft blog is sporting an in-house post-mortem Q&A with lead encounter designer Scott Mercer about their original goals for Cataclysm's raids and adversaries, how they evolved the add-on through post-release content patches, the lessons they learned that are being tapped for Mists of Pandaria, and more. A little something to get you started:
Q. How did this evolve over the various content patches?

Zul'Gurub and Zul'Aman were entertaining raids with diverse mechanics, and they translated well when we converted them into Heroic dungeons for patch 4.1. Interesting mechanics and features that once were restricted to raids are now finding their way into our five-player dungeons.

Adding the Dungeon Journal in patch 4.2 was also a major step forward. We wanted to be able to share more information in the game so that players wouldn't feel the need to go look everything up on external websites. While those sites are great at what they do, we felt like we needed to try to alleviate the need to go out of the game to find the information players wanted to see.

The addition of Raid Finder in patch 4.3 also opened up more opportunities for players to be able to experience our raid content. The feature has proven to be extremely popular, and not just with people who had given up on raiding. Many players use Raid Finder to gear up their secondary characters, gain Valor for the week, or just because it's fun.

Q. What have you learned from Cataclysm and what are some of your top goals for Mists of Pandaria?

We learned we could create a crazy encounter like the Spine of Deathwing. It took a lot of hard work from the whole team and it was a difficult design challenge to tackle. How do you orchestrate a fight on the back of a gigantic flying dragon without inducing nausea? How do we make sure you feel like you're on Deathwing? Delivering that experience was really important and everyone wanted the opportunity to work on it. What was really great was that we launched the story of Cataclysm with the cinematic that showed Deathwing having his elementium plates being put on, then we end the expansion with those very same plates being torn off. It gives some real closure to storyline.
