Blizzard Entertainment is implementing significant changes to the information accessible to combat addon creators in World of Warcraft Midnight, which will affect popular addons like WeakAuras. The WeakAuras team has announced they will not support the addon in the upcoming expansion due to the introduction of 'secret values' that conceal combat-related information. The team believes these changes hinder the core functionality of WeakAuras, which relies on tracking personal combat states. Major changes include restrictions on addons' ability to send and receive chat messages during combat, concealment of NPC identities and buffs/debuffs, and obscuring personal combat states. Game director Ion Hazzikostas stated that the goal of these changes is to prevent addons from providing a competitive advantage over players using the base user interface. The WeakAuras team feels that Blizzard's approach is incompatible with their addon’s purpose and has criticized the communication regarding these changes. Players may need to find alternative solutions for their addon needs in the Midnight expansion.
