I don't think so. It has its lot of cool fights; Anomaly, Trilliax (even if they're too easy), Star Augur, Elisande and Gul'dan are pretty great. And there's only 1 fight I outright dislike, Spellblade. Which is more than I can say for BRF where I hated Ore, Furnace and Maidens.
Albeit Nighthold doesn't have a fight that is as cool as Operator. But he's kinda in a league of his own because I love the concept of a boss killing us by having trains ram the raid.
