Alliance And Horde

The argument whether Blizzard favors Alliance or Horde narratively goes back to the game's release and has never truly abated whether the expansion focused on the faction war (Battle for Azeroth) or saw it pushed aside entirely to deal with a common threat (Legion).

Warbands may be the biggest change coming in The War Within expansion later this year: it's a new account progression system that fundamentally changes how your characters and account function.
