I've seen soooo many people use thrusters to force an enemy cap to engage cruise, just so they could get them out of the system. This rule really needs some refining.
The problem here is that thrusters arent counted as disengaging/fleeing, even when you go out to extreme distances (3-4k from the enemy, outside of max weapon range).
It allows the fighters/bombers to easily hit and run, and shield run, when the capship is helpless without 'breaking the rules' to catch up.
