I felt like on normal they took so long it made me not want to do them again. Plus, the loot structure sucks. I don't want to do them multiple times and collect multiple trinkets to get the gear. I just didn't find the experience fun. The fights were fine. The mechanics made sense. It just took way too long to kill. And given the groups failed multiple times, it took even longer. It was something I wasn't going to do twice.
