I feel like Glaives were something that started off as a very cool and powerful idea, but then got reigned in hard. Like their stabbing melee doesn’t have the element of the glaive. Most perks do not trigger on a melee kill. In first person the tip of the glaive’s blade is way shorter than it is in third person. Which means when you melee you’re missing range. And then there’s the exotics that are weaker than actual class abilities or even other exotics. The whole “build energy with projectile kills” mechanic killed these glaives.
