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.
Ebony mimics now give 2 random items in addition to golden mimic loot, which is crazy since you can get that on every single floor with some luck.
