Personally, I love the changes made in the recent patch, I had been playing a lot with 6 challenges and had into darkness as one, so when I saw an enemy with huntress mind vision not auto targeting them was annoying.
The buffs to ebony mimics drops is nice too, since there is a substantial increase in difficulty.
What would be nice is if the sundial gave a small benefit, like maybe a small boost in luck, to compensate for the additional difficulty.
