The second episode of the official Blizzard Podcast, BlizzCast, is now available! It begins with none other than our Vice President of Creative Development Chris Metzen who shares his thoughts and experiences on building the stories for our franchises. From the origin of Starcraft to the conceptual stage of continuing stories in Wrath of the Lich King and Starcraft II, we get to share with you his point of view on making some of the most epic stories weve ever had a chance to play.

We also got a chance to sit down with one of our raid designers, Geoff Goodman, to discuss the evolution of the raid dungeon encounter Magtheridon and the changes it will see in patch 2.4. Then thanks to the response from our players and fans we finish with a Q&A session that has information on Starcraft lore and World of Warcraft design changes.

Both episodes 1 and 2 are available right now here at the BlizzCast webpage: http://us.blizzard.com/blizzcast/

To allow players on the PTR to test the encounters after Felymyst, we've decided to disable Felmyst on the PTR. When Felmyst is engaged, she will now kill herself and allow raids to continue on to the encounters afterwards.

As a reminder, Kalecgos and Brutallus are also still disabled at this time.
