I'd say it's already pretty hard to wipe out your opponent with drones, if he's not caught off guard. Given the scenario that the attacker has got access to a system with several relatively unprotected planets, a group of escorts can do the same thing as a drone carrier, and isn't used up in the process. Just like with escorts, mines and/or weapon platforms, bases, or even satellites, can block the attack.

At least from the few games I've seen them used in, it didn't seem like PD really needed to be made tougher on drones. I saw PD wasting drones pretty easily. If you lost a colony with a couple of WP's on it to one drone, and one of the WP's was a PD WP, then I expect either it was an expensive high-tech drone or a low-tech PD WP, or both.
