Update: Blizzard doesn't release actual sub counts anymore and they use "hours played" as a metric, not accounts paid. This is a picture of a slide from one of their investors meetings in May 2017. People spent over 40 BILLION total hours playing Blizzard games in 2016, that's insane. While Blizzard is doing well with all games combined and the last expansion edged out the previous one the concensus is that they are holding onto a lot of accounts via their tokens for gold scheme and the game feels much less played.

edit: 40 billion hours = 1666666666.66666... days. I told you Blizzard was evil, 666 to the max!
