Sigh, when you people will learn that these are just empty words. It's very likely that new expansion will bring "sense of wonder, exploration yada yada" on launch, maybe if we are lucky it will last few more weeks like Legion or Classic.
But it's impossible that everyone will run on grass holding hands after that. Especially now when you have so many releases, people know how spread info with speed of light and attention span is so low.
It's just a game, man. You will be bored eventually no matter what. It's better to enjoy real things than chase impossible ideals.
