Which represents the highest sudden subscription increase for an expansion in its history. Over 2.6 million more people subscribed to the game within the last two months compared to the 900 thousand or so that subscribed to it within 3 months of Mists of Pandaria's launch. This also means that Warlords of Draenor has, for now, managed to make back all of the subscriptions lost during Mists of Pandaria. As the expansion just launched today in South Korea, China, Taiwan, Hong Kong, and Macau it is likely that the subscription count will go higher.
