Are those Blizzard apps on iOS, or on the Mac? As far as I know, on iOS, you have to offer in-app purchases for subscriptions, unless you meet specific criteria -- you may be able to offer subscriptions outside IAP in addition, but you need to let people buy in the app. (On the Mac, though, none of this really applies.)
