I've recently began farming destroyer cores in HM with the help of "I am Unstoppable!" and Ebon Battle Standard of courage. Both of these skills provide a +24 boost in armor allowing for a total of +48.
Now I never realized this until just recently but this seems to ignore the armor cap. I've tried the farm using just one of the 2 skills and spirit rift annihilates me when I don't have both up thus leading me to believe they are indeed stacking for a +48 increase in armor.
So is it that wards don't count towards the armor cap or is it something special with pve skils?
