The World of Warcraft WoW pre-patch is here before the release of Dragonflight. Is it necessary to buy the expansion to access the content?
Yes and no. First of all, it is not necessary to buy the WoW Dragonflight expansion to take advantage of the new features of the pre-patch. For now, as of October 26, 2022, only the new talent system has been implemented in the game, along with the new interface. You don't need to own the expansion to use these features.
However, from November 16, 2022, it will be necessary to have the Dragonflight expansion if you want to play the new class: Evoker.
It goes without saying that on the day of the expansion's release, it is mandatory to have a Dragonflight edition to access the dragon islands and level up your character to level 70.
