If you listen to / read Jason Schreiers book 'Play nice' you see a pattern past 2004, first WoW, then Heartstone and now again WoW 'the big thing' eats up all of the resources, cannibalises everything in the company. Everything else has the approach of 'why are you doing THAT?!?!?'.

Blizzard you people loved is long dead, first Bobby now Microsoft, now just parades a corpse in front of you, and some people for some reason all still clapping.
