In the 4Q, 2014 (Warlords of Draenor was released in Nov. 2014), the number of subs bounced from a low of about 7M up to 10M. But that dropped back down to 7.1 M the following quarter.
As on June 2015, the number of subs had dropped to 5.6 M.
So, while there was a nice bump for a few months, the expansion's dungeons and raids didn't keep the numbers up.
