@McNeo: If I'm in a fighter, fleeing/disengaging/whatever and someone cruises after me in a capship and theres other members of the faciton I'm in on, then I'll consider that I'm luring an enemy into a trap and try to do exactly that.
Otherwise I'll lead them on a long and pointless <strike>dance</strike> chase and then consider that a capship wasting time, fuel and energy on chasing a lone fighter a victory for whatever faction my fighter belongs to.
If I'm the one in a capship, I'll only chase another capship and then only if I consider it worth it, otherwise I'll hammer them and let them run off.
