It was cute in Legion where we mostly fought humanoids, demons and beasts but WoW has kept moving on with the types of enemies you deal with.
If you’re in a dungeon like Necrotic Wake you basically only have CHaos Nova ( and Eruption if talented, but you don’t take that for some builds ) as crowd control. And that’s whack.
We’re already a class with pretty limited CC, Imprison has a long cooldown and breaks on damage, it’s about time it started working on any type of enemy. Undead and Aberrations as a minimum.
