It’s hard to be certain that this is unprecedented, but it’s certainly unusual for World of Warcraft. A former player has posted on Reddit about a survey received from Blizzard covering Battle for Azeroth: whether it made the game better or worse, what was wrong with it, and what could be done to improve it. There was even a post-survey question about taking a Skype call to voice feedback for further understanding.
Of course, it’s one person posting this with no overall certainty about who receives this particular survey and why. (The follow-up about a Skype discussion is specifically noted to be with “select individuals.”) It still sounds like a very unusual move for Blizzard, which no doubt makes it sound a touch farfetched… but it also would confirm many theories about how far overall subscriptions have fallen and the general reception of the current expansion.
Or, to put it another way, perhaps we shouldn’t be surprised if this particular expansion mirrors Warlords of Draenor’s patch cycle.
