I am finished with the dlc, and I loved it. I do agree, however, that the stealth sections were way too hard and dampered the otherwise exquisite experience slightly. I did actually beat the stealth part in the Cinder Isles with reduced frights off, which I was proud of, but I had to put reduced frights on for the one in Hidden Gorge, I just couldn't do it. Way too overtuned and difficult.
