No it didn't. Last sub call for wow was about 5.5m subs after a 100k sub drop. Ff14 ARR boasted 2 million sales not subs but sales, like when blizzard talked about the 100million subs created over wow lifespans at start if mop.
Neither game is detailing sub numbers but even square Enix doesn't think they're getting more subs than wow. If they did they'd at least hint at it.
