"World of Warcraft saw expected declines post the expansion release this summer."
How shit of an expansion you have to release to make the number of users drop after a brand new expansion is released.
Historically the biggest increase an expansion gives to WoW subscriber count is in the first 6-12 months - but BFA is so awful it caused a DECLINE in the number of users...
Good thing blizzard has that cash shop to milk players xD
