In addition, In addition, Blizzard is automatically upgrading all existing World of Warcraft subscribers to Legion at no additional cost. That's all changed today, as Blizzard has announced that every single player now has access to the base game and the majority of expansions so long as they remain subscribed.
Personally, it's a great thing moving ahead, as this may gradually change how Blizzard employs their expansion strategies. The monthly subscription fee now offers access to all content up to and including Legion.
What it won't get you though is access to Battle For Azeroth, the seventh expansion which is due out next month and which will set you back an additional £39.99.
As Polygon reports, Blizzard isn't making a big deal of this (yet).
In the past, if you wanted to jump into World of Warcraft, you had to but the Battle Chest, which contained the base game and numerous previously released expansions as a flat, upfront fee, along with needing to fork out for the monthly sub. Well, if you bought any of these items, you technically didn't buy any game, just a fancy piece of cardboard you can put on a shelf. You buy the base game, and the expansions, and then the monthly subscription. This does not include Battle for Azeroth, which comes out on August 14. As part of the Battle for Azeroth pre-patch, you can now engage in "War Mode" in Stormwind or Orgrimarr and toggle on world PVP - cross-realm (the newest experiment in a timeless attempt to appease people who both love and hate world PVP).
