Alpha - I've had them using mostly transports, I thought it seemed to help with the launching all the drones in one battle problem, as they had a large amount of cargo and only a few launch bays. Didn't have too much problem with the small number being launched being overwhelmed by defenses because I have them chasing Colony Ships, transports, and unarmed ships as their primary targets.

Baron - The launching drones into orbit with no targets is part of the percent to keep as cargo line of the Settings file. For drones you should set it to 100 so that the drones are not launched into orbit as soon as they are built.
