I've came across the removal of the cost reduction and it seems that this causes a lot of trouble for the rogue/knight.
I'm not sure, if this class combination is not of interest, but I really like the style and I'm afraid, that it doesn't have endgame potential.
But now already, I can see that my usual rotation doesn't work anymore because I lack energy.
Searing Light cannot be used with energized hands together, so I don't have an option like the rogue/mage using that complementary to Chaos Dagger.
Punishment still doesn't recover mana
