I've learned that blizzard has a very predictable cycle. When an expansion announcement is getting close blizzard starts getting the hardcore players excited by telling them that they've made mistakes in the past and pushed the game too far toward being casual.
Then when the expansion beta gets close more and more info comes out that they're actually pushing the game to be MORE casual
It's been that way for every expansion since lich king.
And you have to keep in mind that they hired the head of PopCap games a few years ago. Popcap is the kings of casual gaming. They've made bejeweled, peggle, and other casual shit.
Blizzard Hires Casual Games Guru From PopCap
The former general manager of Xbox Live Arcade and v.p. at Peggle studio PopCap is going to Blizzard. Let the development speculation begin.
Kotaku has learned that Greg Canessa, the man who ran Xbox Live Arcade at the Xbox 360's launch for Microsoft and has since served as vice president of game platforms at PopCap is joining the team at World of Warcraft and Diablo studio Blizzard.
Blizzard has shown an interest in casual gaming recently, weaving PopCap's popular Peggle game into WoW earlier this year and Bejeweled before it.
Pet battles, Transmogs, Farms, Garrisons, LFR, Flex, Free Epics....There's your reason.
