I understand that Nocturnal Sect wasn't particularly popular, but I wish it hadn't been completely removed. If someone got caught in an AoE right before raid-wide damage was about to go out, an on demand instant shield could save their life. Even if Nocturnal Sect was objectively inferior to both Scholar and Sage, I would still find situational uses for it.

Even if they determined that the shields had to go, I would have liked to see Nocturnal Sect repurposed. Once upon a time, Scholar could choose between Eos or Selene. One for healing and one for utility. They could have tried something similar for Diurnal and Nocturnal. Instead, it's just gone.
