So I jump in my flag ship and a group of frigate to an unoccupied planet. There are a relative big group of pirate there and we engaged each others. About mid way through the battle I jumped a colony ship in from the other side. As soon as the colony ship jump in, all the pirate ships, and I mean the entire fleet disengaged my main fleet and rushed toward the colony ship.
It's cool that the AI has some target priority and chase after the colony ship, but having the entire fleet just turn their back off a wall of fire is kinda extreme. It's an exploit to a sense because my fleet got in many free shots, and then I can move the colony ship around a bit before it got destroyed, the pirate fleet chased it around like kids chasing after Santa dispite my fleet was chasing after them with gun blazing.
