Level 50+ dungeons can be challenging

I think HW's difficulty was in its rotations. I doubt you'd like to do savage needing to toggle clerics, for example. The rotations they had were punishing, forced players to stay in place, and required high skill or you lost significant DPS. If you added hard dungeons to that, you'd have the casual equivalent of HW's first two raids. The difficulty was reflected in the moveset for HW's new classes; all of them were more complex than the ARR jobs, at least at launch, where SB's new jobs are simpler. And the ARR jobs were harder in HW too; BRD and BLM in particular.

I wouldn't know...I was a monk for 3.5 and most of 3.56 before switched to DRK. I did play around a little with WHM...cleric stancing didn't seem too hard, but then again, I wasn't at the point where I could run Alex Savage, though I got close right before SB dropped.
