That's too bad about the defense drones. They're almost like buildable flak drones in some ways. I suppose I have to agree that they can be very cracked in the fact that they make a nearly impenatrable defense for planets against transports cruisers and the like.
Gunboats tend to knock out defense drones fairly quickly though. The Ishiman Gunship can knock over a DD quite quickly, and without too much damage taken. One Gunship could probably take down a large number. And with a large number of gunships, you can take out defense drones. Canth Gunships I would think would do a decent job of it, with that huge-ass gun. Sal would do good, and the Gaitori's can outrange the DD's by magnitudes. Carriers might be torn up a bit, since they might not have the manueverability to dodge a bit, and can't deliver as much DIRECT firepower as a gunship can. But they can take a heavier beating and could probably overwhelm DD's.
As far as evening out the playing field, I once read an article (by Slug?) about Gunships and the like as anti-carrier, Carriers as anti-cruiser and Cruisers are anti-Gunships. Defense drones would fit in (and weapons should be gauged towards) small craft. Therefore, the larger ships would plow through but the DD's would be able to repel smaller forces, such as those of small, fast ships making a disruptive raid. Or to repel tranports. It'd add an interesting aspect to tactics and strategy. It would add in the aspect of hardened bases and the task of assaulting them.
Besides, nobody in their right mind would focus on DD's. Like so many strategists have said, one can never win a battle from the defensive. So, if you built up the hugest defense in the game, invariably the person who's been building HVD's, Carriers, Gunships and cruisers will sail in and whomp your ass, since all you have are DD's. You'll lose, no matter how many you have. So, perhaps Defense drone's aren't as bad as some people originally thought.
