Blizzard has explained in a Forum Post that the Block interaction on Anub'arak is working as intended, which means «Block sets» for tanks won't be as powerful as players predicted.
Greetings, Wanted to chime in and confirm that this is working as intended and at this time we do not intend to change it.There was a bug fix late in original Wrath that caused the game to calculate damage with multipliers (including Expose Weakness) before block was applied. This fix was made specifically in response to how the Anub’arak encounter behaved in ToGC in 2009.
As the fix was systemic to how multiplying/stacking damage is calculated, a reversion here would be global and impact all combat and encounters in Wrath Classic, and going back and deliberately “breaking” an aspect of gameplay to recreate a specific interaction that was unintended even at the time isn’t something we generally prefer to do. This fight is perfectly manageable now in its current form even in pick-up groups, as evidenced by the many many kills that occurred on PTR.
