So drones are, obviously, unmanned vehicles that we can take with us into space and kill things with. But how do you envision them in-universe?
I’d like to imagine there’s a blend of both AI-controlled drones, and crew-controlled drones. The smaller ships probably rely on AI moreso than bigger ships, of which have more crew and resources to dedicate to drone control bays. Sure it doesn’t make sense that you skilling up makes your crew better, but neither does it make sense that skilling up makes your ship AI better. And it’s said that the more modules you have on your ship, the more crew you have as well to operate that equiptment. I don’t see why it would be any different with USVs.
Perhaps it could be that Gallente ships have inherent bonuses because they utilize more sophisticated AI, where as the other empires use flesh and blood crew to man their drones? Who knows, unless CCP come out with something then I guess the interpretation is up to the reader.
