"There has been less engagement by casual players"
What does this actually mean or what do you think they mean by this?
Do they mean that the casual players have been leaving the genre? That they've been catered to, but don't actually appreciate what they're offered? Or is it just impossible to retain casual players easily since they just hop from game to game without feeling commited to play anything longer than the short while they get enjoyment out of it?
Does this mean Blizzard wants to focus more on making casual players feel engaged? To cater more content and game design to making the 'casuals' feel like they should stick around and play a bit more?
Or does it mean that Blizzard is kinda feeling that they can't control what casual players do or how much time they decide to spend on the game and that they should be aiming to focus more on their loyal and dedicated hardcore raider and pvp scene instead?
