But it's correct though. The WoW population that's been playing since vanilla/tbc are aging. The game is a decade old, in that time people finish studying, they start full time work, maybe they get married, maybe they have kids, they certainly don't have as much spare time anymore.
Sure sub numbers went up 3 million, but they went down 3 million as well, and I'd wager a large part of that was people getting hyped up, experiencing the leveling content, and then quitting. Which is pretty much what myself and my partner did. And that's fine, I would assume that Blizzard actually kind of expected something like that to happen as they realise that a lot of their core player base, the ones that have been playing for a number of years, don't have as much free time to play any more.
With tokens being introduced, I'm considering a resub, if only to check out tanaan and stuff, and just chill out and level alts sometimes or something. Did enjoy playing with my partner, even if I don't really have time to even do lfr anymore.
