Problem, drones have no pilot. Hence no waypoints. You'd have to jump your ship in, undock the drones, and jump out. Which is exactly what we've been doing with larger ships. Doing it individually would be... well... pointless. One drone is an easy kill, 200.. not so much. But having to jump 200 times would not only take forever, it'd end up being meaningless.
So yeah, without some sort of automated waypoint system, or fleet waypoint commands... can't really see the drones knowing where to go without jumping inside and trolling about.
Making a jump rack is also meaningless as one ship can hold multiple racks and do the exact same job @ 10+ times the speed.
Kinda back to square one here
