I don't think HW had bad encounters at all. If anything it suffers from the stigma of A1 and A2 and their savage versions that were extremely underwhelming and essentially glorified dps checks. Rest of the alex raids are pretty great, they also still have more than just a boss to hit for each fight as well as a bigger care to their actual environment. Shadow of Mhach also suffered from a first tier that even YoshiP apologized for how much of a boredom it was, and then we got gems like Weeping City and Dun Scaith (bring back the the old gate boss and remove proto ultima or move it somewhere else please, the old one was hilarious and the casualties were great kthx).
