Drones cannot be put in fleets, so that makes them more vulnerable in battles as well. The "shift-click" thing did not work Last time I tried.

Drones may be controlled once they are launched, with the "attack" order; this allows drones to travel through wormholes, or to attack a specific target, but no more than that.

I would use drones in specific games, such as games with a ship limit of 200, high-tech games (drones make the best scouts then), or a game with mines disabled, or perhaps even to help a wormhole blockade along with fighters and the like. Are drones refueled by resupply depots? Hmm...
