It's been a long while since our last major balance patch. Please see our follow up post for updates to this preview as well.
The name change will be part of a build later this month. This only affects the trait's name, not any functionality.
The name change for the Revenant trait 'Spiritual Reckoning' will not be part of the May 11 update, and we have removed 'This trait has been renamed Spiritual Resolution' from the notes below.
