This is a great summary of the grievance BFA left in people at large. As some have stated the questing experience in Kul Tiras and Zandalar was pretty good, and I felt they nailed the landscape/city design as well (well, Dazar'Alor is a bit unwieldy...). The expansion had great footing.
Then the writer's team took bad acid and went ham on the main plot. Good god, I wonder what's going on there right now. Are they even aware how their customers feel about their output?
