Update: some buffs have gone live today, with changes to how artifact traits affect DPS and healers.
Blizzard have addressed the dominant tank meta taking hold of Legion remix. They will be implementing buffs to DPS and healer specs to compensate 5-tank Mythic+ groups taking over the place! We didn’t get any specifics, but they will be coming with next week’s reset and Phase of Remix.
We are currently aware of the tank meta in high level Mythic+ keystones and have some targeted buffs for damage dealing and healer specializations coming with the release of Phase 2 on Tuesday.
