As an "adult" WoW player who took a WoW hiatus from late Cataclysm to late WoD (to try pretty much every major competitor), I've returned with a very pronounced "good enough is good enough" attitude spurred on by the fact that Blizzard is competing for and intelligently winning my time by creating a minimalist and accessible main thoroughfare to their PVE game and storytelling. World quests are a masterstroke and a condition for my further patronage (a condition I predict will be emphatically met), raiding above LFR and 5-mans above heroic are certainly not worth my time, and I can't summon a single f*** to give about them.
Power is inevitable and fleeting, access is all that matters, and that comes with the subscription. WoW remains "apply time, wait for catch up mechanics and win," thus I am a happy and continued customer.
