They are still too expensive for their performance. The have great stats, and can live way longer than they have any right too(like some other 3 Agi ships) but one round of bad rolls and you can lose one(like any other 3 Agi ships). They don't have any linked actions and they don't have any special action economy beyond the Advanced Droid Brain which is comparable to just having the Focus action. Going along this same line, their attacks seem a little weak because they generally need to be taking Calculate actions for offense and defense so they end up without the ability to modify blanks unless you have an Escape Pod handy to coordinate them a Target Lock. Adv Sensors helps them a lot, but because of the one action limitation it has no synergy with Charlie's free Evade after boost ability.
Either all of the IGs need another round of points decreases or their favorite toys need to come down in points. Advanced Sensors and the title both come to mind. If you could run 2 Aggressors with Adv Sensors and still have enough points for a meaningful 3rd ship they would see some play.
A new system upgrade in the vein of Advanced Optics but using Calculate tokens to modify blank results could be useful if the price is right, but generally I don't like to dream up new upgrades. I try to work with what we got.
