How NQ plans to implement turrets, or combat for that matter is pure conjecture at this point.
However,
With ANY game that has AI, there is a balance that needs to be achieved. Since the AI in a computer can be a crack shot, and always place that round through your right eye, programmers need to balance AI accuracy with realism, player challenge, and player enjoyment. Players want "Realism", but they also want to progress in the game. They just don't want to progress too easily.
