The latest edition of Blizzard Insider, Blizzard's very sporadic email newsletter (and no relation to our old name, WoW Insider) has been released. Issue 32 features a note that the Starcraft II: WIngs of Liberty site has been revamped, blurbs about the mobile Authenticator and the Armory app, and some calls to buy their merchandise.
More interesting for WoW fans, though, is an interview with Scott Mercer (Daelo), WoW's lead encounter designer, and Greg Street (Ghostcrawler), a crab who needs no introduction. They discussed the arc of Arthas and the Lich King from Warcraft II through World of Warcraft (congratulations again to Blood Legion on their 10-man world-first).
Please note that here there be spoilers for some details about the Arthas fight, so stay away if you want it all to be a surprise.
