What happens if, with larger ships, you send in fighters to take the shields down and then a swarm of Argos come to lock on and immobilize the ship?

Theoretically, yeah. Because it's all physicalized, I'm not going to say it's going to be easy to do, but if you had a wave of attack ships to take down a capital ship's shields, theoretically, yes, those Argos could try and move it somewhere, bearing in mind, again, power, mass. That ship's not going to have its shields down forever, and as soon as those shields come up, that's going to be a problem. And also that ship is probably not going to be not shooting at all those people doing that.
