What you were expecting to happen, and what actually happened:
I was expecting gem masteries to work at their proper percentage, however they were working at around 25% instead of 60 to 65%. No enenmies with halve gem materies.
How often does this happen? When did it begin happening?
It happens regularly in all game modes, but it has been getting worse. Tower of doom and new faction quest have been particularly bad.
Steps to make it happen again
Play any game mode. Very frustrating when AI has no trouble powering up and it takes many turns to get anything of mine ready.
