That's disingenuous. Blizzard may have said that difficulty caused the subscription decline in tier eleven, but even if was true they wouldn't come out and say that LFR was the cause of the subscription declines during tier thirteen and fourteen. They only addressed the tier eleven difficulty issue after they'd decided to change it. The lack of blue confirmation doesn't make it any less probable that LFR contributed to subscription declines in the middle of tier thirteen and fourteen.
