Why do Gatts ignore starships?

[triggerman602]

Why is it the Gatts completely ignore starships until everything else in the system has been killed off? they dont even shoot at them as they pass by. if there is some hidden strategy that they are trying to do by getting shot up by starships and not retaliating then i think they could use an upgrade to there logic because at present i dont see any good reason why they would behave like this.
