Blizzcon is going to be very interesting considering they didn't have it in 2012 and there's still unrest around WoW and Diablo III and even Starcraft II with the recent decisions that have been made. Granted, Blizzard does have time to see what they can do to potentially rectify and smooth things over with the fans, but if not...Blizzcon is going to be very tense to say the least.
As far as the video...gotta say I like this one better than the DH guide one. That one was just very poorly done, too much misinformation given, and didn't touch upon some of the better gear choices while outright dismissing and downplaying the rather good new Natalya's set and its 20 Discipline bonus. At least if you're going to make a gearing guide you should cover more bases and show people more possibilities for gearing characters.
