I definitely expect to see Tractor Beams find their way into Dual Aggressor lists. While it's true that the TB doesn't do direct damage itself, the ability to put an opponents ship on a rock could be a very strong option at a given point in a match. Self-preservation is one of the keys to flying Bro Bots. Putting a ship on a rock and then having your fellow bot take a shot at a reduced agility ship could offset a bit of that non-damaging effect.
It's certainly situational and there would be matches you wouldn't want to use it at all but at just a single point per ship in an otherwise empty slot it can be a great trick to have up your sleeve if the right opportunity arises.
Moving them from 2 to 3 to trigger AT while still shooting at them with HLC ignoring the range evade bonus + decreased agility sounds decent.
