Allegiance Subverters - annoying or what?

Yeah, only one shot. I entered into combat with my three ships, 2 old model cruisers and on top of the line battlecruiser (the only things defending that system which was highly inaccessable due to damaging warp point) whent into combat with one ship.
They took my battlecruiser and used it to destroy my cruisers. After combat they had two ships in a defenseless system. (not even a weapons platform or satelite) so what do they do? They leave. Hmmm.... that makes sense.
