We’ve investigated this issue thoroughly and we believe that resists are now functioning more closely to original Burning Crusade.
During the development of patch 2.5.2 for Burning Crusade Classic, we found and fixed a bug preventing some talents that resisted specific mechanics (such as Unbreakable Will or Surefooted) from combining with school-based resistance stats correctly. The bug resulted in resist chances in patch 2.5.1 that were slightly different than the original 2.4.3 Burning Crusade.
As part of this fix, we took a close look at how the resist chance formula changed between patches 1.12.0 and 2.4.3. This led us to discover several pertinent changes that had happened over the course of the development of original Burning Crusade. These included alterations to the order in which spell hits and spell resistances are applied. We brought those fixes into Burning Crusade Classic patch 2.5.2, and we’re now confident that our Burning Crusade Classic resist chance formula is accurately mirroring the behavior of original Burning Crusade patch 2.4.3.
The bugfix resulted in some changes that we initially overlooked but have now identified. Two notable examples are:
-
Excess spell hit can no longer be used to cancel out the effects of talents that resist certain mechanics, such as Unbreakable Will.
- This rule was introduced in patch 2.4.0 of original Burning Crusade, and we’ve based all other underlying game mechanics and formulas on patch 2.4.3.
-
Rogue’s Cloak of Shadows now correctly resists spells at 90% in PvP, instead of 80%.
- This was first reported to be 80% in the beta for original Burning Crusade. However, a later change to the resist formula during that Beta resulted in Cloak of Shadows granting 90% resist chance in PvP. Ultimately, original Burning Crusade launched with Cloak of Shadows resisting at 90%, and that was not changed throughout the original expansion.
We apologize for our delayed communication on this topic. We investigate these bug reports as they come in, and we’re confident that the updates to spell resist formulas have consistently brought us closer to what existed in the original Burning Crusade.
Thank you.
