The Dragonflights kept to themselves, international organizations like the Argent Crusade, Tirisgarde and whatnot did not exist or were at least not in focus. Nowadays people from Pandaria, northern Kalimdor, Northrend and southern Eastern Kingdoms (and beyond!) can talk to each other and band together at a moment's notice if required; Legion showcased that quite well. Thus, the Horde being needed for the world's defense seems increasingly less credible, especially after Garrosh and Sylvanas's antics.
