It feels like I can get literally everything I want on a Drover and then some. I can quite reasonably fit four small missiles, expanded missile racks, two 12~ OP fighters, a pair of machine guns and almost 20 OP into capacitors. There is no 'Oh I want to focus on fighters more than these small missiles' style choice.
I could fit a 'good' Drover with 40 OP. It would have two Broadswords(16), four Harpoons(12) and Expanded Missile Racks(12). A bit light on fighters, and no ballistic weapons, but four Harpoons with Expanded Missile Racks is pretty good.
Drover should probably have 45 OP, same as the Condor. Or maybe they should both be 55. Or the Drover should lose a flight deck and get more missiles.
Actually, compared to the Condor, the Drover seems really out of line. I don't see an area where the Condor is better than the Drover.
