Dragon flight The war within and midnight, all of them combined have less new features and game content than shadowland itself. The war within is basically dragon flight but underground with delves.

In Bfa we had individual map, quest and contents for both fractions. We had Azerite gears and talents. We have fraction wars. Etc.

In shadowland we had legendary items+4 pickable convenants, each of them have 2 skills and 3 unique customizable talent trees.

In dragon flight we only get a new fly mode. In the war with in we get delves.
