Surprise surprise, people have different opinions on things. Anything else you just discovered?
Personally I am enjoying Torghast so far. It's pretty challenging, but not hard enough for me not to be able to beat it. Some of the anima powers are crazy and make the gameplay very interesting. Love running it, especially with friends.
Some people are criticizing the length, but personally I can't really see myself running 70 floors of this in a row. Getting through a 6-floor layer takes us about 30-40 minutes depending on RNG and I think that's just enough of time I want to devote at one time. If I'm feeling the need for more, I just run the 2nd torghast option. The endless corridors or whatever it's called might be fun, but if it's as long as 30 floors in a row, I will have to set aside a lot of time for it.
The theme of SL seems to be that a lot of the content is optional and not tied to player power. So if you don't like it...just don't do it. It's pretty simple
