Blizzard's Deep Dive WoW panel revealed additional details on the new Hero Talents system providing a brief overview of how the new system will work in The War Within Expansion.
Hero Talents are evergreen self-contained talent trees that bring additional fantasy to your class experience by bringing iconic Warcraft archetypes.
As an example, Blizzard walked through the Balance Druid Hero Talent trees to display how these might work. Keeper of the Grove talents are shared with Balance and Restoration Druids and focus on improving your character by focusing on Treants and the power of nature. Elune's Chosen primarily focuses on Lunar spells and is shared between Balance and Guardian Druids.
How Hero Talents Work:
Blizzard ended the Deep Dive panel by revealing the full list of Hero Talent spec names available for all 13 classes. The full set of Hero Talents should be available for testing when Alpha launches in Spring 2024.
