Correct me if I’m wrong, but they didn’t initially imply that the cloning service would only be offered temporarily, did they? I know that eventually they made a forum post saying it was ending, but… sure, and I understand the service was available for a year, but come on… no one ever thought it would go away. Of course, until they said it would, which by that point, people who missed the window were understandably not looking at their Battle.net launcher or checking WoW forums for any number of valid reasons. The expectation here is absurd; no one knew it was going to eventually go away.
(unless you were one of 7,000 people who checked this forum post here:)
