In the great annals of history, World of Warcraft’s Patch 7.3.2 isn’t going to warrant even a footnote or throwaway citation. And yet it does have some of the game’s players genuinely excited, because the patch is being used as a preparation point for the upcoming Antorus raid.
So while the raid isn’t here yet, 7.3.2 means that it is coming soon, and that is noteworthy for the time being.
Other than a few small class and item adjustments, the patch also adds new legendary tokens. These tokens only drop when a player has attained all of his or her class’ legendary items. The token then can be used in an exchange for a legendary on another spec or alternative character.
