This seems to have gone un-noticed by most, here was the Q3 investors call transcript:

If this was already posted my bad, but I couldn't find it.
Here was one particular question and answer that peaked my interest:
Can you discuss in a little more detail recent performance, and trends you are seeing across World of Warcraft and Hearthstone; and how you are thinking about the pace of investments for these franchises going forward?
Morhaime: So we continue to be very happy with both of those. With the strength of both of those franchises; and I would tell you on the World of Warcraft side, we are investing more than ever.
The team has been hard at work delivering on our commitment to the community to deliver more content, more consistently between expansions, that has been going really well. Since Legion was launched in August of last year, we have added multiple content updates, and the updates have been really well received by the community.
We have seen engagement up versus last year, when you look at time spent per player, and also frequency of play.
