Drone questions!

[sachmo]

Still a newbie, so I get to ask silly questions!

1. Is there a way to group drones? I know they can't be fleeted, but if the only way to move them is with shift-click, doesn't that mean that when they attack a fleet, they will enter combat one at a time??

2. I tested my drones in a simulation against an enemy ship with only missiles and PD weapons. In the simulator, he moved into attack range, but was unable (or unwilling) to fire at the drones. Are they like satellites in that respect, or was it an AI problem?

3. Do drones have accuracy, or do they always hit?

4. If I create a drone with an anti-planet warhead, can I attack any planet not controlled by me, or does it have to have an enemy colony on it?

Thanks!
