My point (if I've failed to get it across) is that we are applying human ideals and methods of thinking to an alien species. If we reach the points where Drones can obtain enough independence to effectively vote (under the right circumstances), then I feel we've strayed too far from what makes the Hivers an alien species.
I understand where you're coming from. I'll try to explain my point of view, briefly.
I have several reasons for preferring my version. One, unfortunately, is basically that it is indeed a somewhat less alien concept. That is, it's more relatable; easier to get one's head around. Which, in a way, makes it more exotic, I think- if something is
completely foreign, it becomes meaningless, but if there are aspects that are recognisable, the bits that are different are more glaring. Plus, for the purposes of interacting with the other factions, I think having there be some common ground is useful, just to make things more interesting.
Also, I find morally ambiguous factions more interesting, and your version of drones has basically no moral ambiguity.
Also also, it just feels more realistic to me. Having some members of a species be sapient, and other members totally lacking in even the
capacity for sapience is just weird. I mean, even in the Hymenoptera family, the workers have (vestigial) reproductive systems- and in most other eusocial animals, the workers are genetically the same as the royalty, but have their reproductive systems suppressed using pheromones. So it makes more sense- especially if we're going by the Precursor lore that states that Hivers are descended from non-eusocial sapient insects- that drones have 'vestigial' sapience, as it were.
