Physical mitigations missing
 

I am using a slightly modified version of the burt player window. This UI lists the physical mitigations: slash, crush, and pierce. These things are good to know for a tank.

I believe it was after the 4/20 patch, these stopped working. The read all 0 now.

Anyone have similar problems or know how to fix this?

Those values were never intended to be used. Its no surprise SOE finally got around to disabling them. And yes they are disabled everywhere.
