I still find this hard to believe. Sounds like an extreme oversight. I will have to test that myself. My WAR can get 38% DA rate, with Atma of the Lion, Atma of the Rapid Reptilian and Atma of the Apocalypse the tests shouldn't be too bad.

Three possible scenarios:
1. DA first
Expected DA rate: 38.0%
Expected TA rate: 19.6%

2. TA first
Expected DA rate: 27.6%
Expected TA rate: 30.0%

3. Both exclude each other
Expected DA rate: 38.0%
Expected TA rate: 30.0%

4. They cancel each other out
Expected DA rate: 27.6%
Expected TA rate: 19.6%

Should be easy enough to determine which one it is.. if this thread is correct, it should be option #4.
