Patches and hotfixes
Hotfix (2020-03-20): Restrictions on acquiring role-specific Azerite Essences from MOTHER have been lifted. Rank 3 tanking, healing, and damage-specific Essences are now grouped together and can be purchased with [Echoes of Ny'alotha] when at least one is unlocked on a character.
Developers' note: This update to the new Echoes of Ny'alotha system is intended to make Essences much more available to your characters whose specializations put them in different roles [...]. A side-effect of this change is that even a single character now has a way to obtain these off-role Essences, and can either use Echoes to purchase them from MOTHER or use the original means of acquisition.
