The Heart of Azeroth is the big new expansion improvement players will be contending with in World of Warcraft: Battle for Azeroth. We know how it’s meant to work, but we haven’t yet seen any of its traits actually in operation… until now. The most recent build of the game’s alpha has added in a handful of traits and effects for Hunters and Shamans, both classes that share the same armor type. This would indicate that more traits are likely being finalized, so this serves as a vanguard to more abilities.
The current list of traits feature some distinct abilities per class (boosting the Astral Shift damage reduction for Shaman while improving Aspect of the Cheetah for Hunter) and some universal traits, such as increasing movement speed based on Haste or granting attacks splash damage on each target. Obviously, the trait list is incomplete at this time, but it should provide a hint about what your various bits of armor will offer you once the system goes live with the expansion.
