For traits that go beyond simple numerical changes and have their own identity—such as active abilities or the powerful and noticeable procs—we are on the lookout across all specs for a small selection of traits that are worth turning into permanent parts of a class. The bar is high for a trait to become permanent. It’s an intended part of the experience of a system like Artifacts that the bonuses are layered on top of the core functionality of your class. You get to explore those bonuses thoroughly, but eventually move on from them. That leaves space in the permanent classes for new special bonuses from other systems in the future, as we’ll soon be exploring with Azerite Armor. That said, various specs will likely see one or two familiar traits from Artifacts showing up in their talent trees in Battle for Azeroth.
