WoW forum user Garyoak posted a list of observations regarding Ulduar boss mechanics and health pools on the Wrath Classic PTR, to which Blizzard responded. It seems that the definition of “pre-nerf” is a bit broader than many might have expected and Blizzard looks to potentially make more tuning changes to Ulduar Bosses.
This is a really helpful list, Garyoak. Thank you!
