Visually, Scholo and the two SMs are nothing like they used to be. Similar 'style' but you can immediately tell that all the art is new.
Scholo has boring bosses? what? I love those bosses. Jandice is an AWESOME concept and is genuinely rough to do 'correctly'. Rattlegore is interesting, and Gandling is as cool as he always was except without the 6 rooms of garbage before him. Oh, the first boss is cool too just way undertuned of course.
Scarlet Halls has dog food trash, which is awesome aside from when it bugs out, Harlan is probably the least-pug friendly heroic boss in the expansion, and the last guy is neat, try not blocking book burner sometime and see how much more fun it is
Cathedral..that one is mostly unchanged. The monk boss is a lot of fun, but the first one is kind of a snooze and the last boss is way too similar to how it used to be. Also this zone on challenge mode SUCKS BALLS. Tuned too tightly compared to most of the rest imo.
