I haven't done this in practice, but couldn't you just blap a couple of them, jump out, wait for shields to recharge, jump back in, and repeat? The AI is retarded, so if you selectively engage the swarm or avoid it then it becomes useless.
That or use a dedicated swarm missile ship. Swarm missiles > swarm fleet. (This I have tested, and it works well). The challenge then becomed to predict what the enemy will use, which turns into fun strategy.
Just to elaborate further - due to the 2mil e/s power softcap, and with how AI strafe + high TMR works, you can make it extremely difficult for the majority of large ships to do any damage whatsoever. Since almost all ships will buckle after shields drop, massive collective DPS from drones can be absolutely astounding. Of course, actual DPS is less than the maximum DPS, but all the same, it's magnitudes more efficient economically.This part here. Swarm Missiles don't work vs any of my drone fleets because of a combination of AMS Drones and AMS Turrets on the main damage dealer drones. You'd be lucky to see them leave the barrel in a fight with me. XD
