"The Battle for Azeroth pre-patch is here, and with this update we’re making some exciting changes to the way players access to World of Warcraft. Starting today, new players can gain access to all World of Warcraft content up through and including the Legion expansion simply by becoming a subscriber—you no longer need to purchase the original World of Warcraft base game. In addition, all existing World of Warcraft subscribers have automatically been upgraded to Legion at no additional cost."
This is part of a push to get more World of Warcraft players but I wonder what the overall end game is? All other MMO's seem to be free to play and I wonder if World of Warcraft will ever go that route? They make a ton on monthly subscriptions but I wonder a World where you can play Warcraft without a monthly sub? Any case it's a long time coming but I suppose time will tell.
