World of Warcraft's controversial decision to restrict combat-related information accessible by add-ons, introduced with the Midnight expansion, is permanent. Game Director Ion Hazzikostas has affirmed the success of these changes, acknowledging that further refinement is planned.

These alterations significantly impacted community-developed tools, many of which were deeply integrated into the player experience for parsing combat data. Blizzard simultaneously introduced new first-party UI tools to mitigate the disruption. Hazzikostas explained that the primary goal was to create a more accessible game and a fairer environment. He noted that the reliance on powerful combat add-ons had previously compelled the development team to design encounters around their existence, a practice he wished to move away from.

"I know this may be a controversial statement," Hazzikostas told PCGamesN, "but I will say that, overall, [the new UI] has been successful so far." He admitted that the system is not perfect and that Update 12.1 will include a "more comprehensive overhaul" of the add-on system. Despite the ongoing adjustments, Hazzikostas reported that the majority of players continue to complete content at a similar rate to before, with fewer feeling the necessity to rely on external tools. The changes aim to improve the experience for new players unfamiliar with add-ons and to shift encounter and class design away from dependence on third-party information.

World of Warcraft continues to support add-on development, with Update 12.1 aiming to streamline the creation process for the community while simultaneously closing loopholes that allowed add-ons to access data Blizzard intends to keep private. This approach differs from a strict no-add-on policy, such as that seen in Final Fantasy XIV. The game's combat add-on policy, though divisive, appears to be a fixed element of the World of Warcraft experience moving forward.
