when a warship engages cruise to catch up if you have NOT engaged cruise before - it is violating the rules and can be reported ( if you feel that its important enough to file a report about it )
if you have engaged cruise ( hence you are considered fleeing and should be on your way out of the system on the shortest way possible ) - the capital ship can engage cruise itself anyway.
so it is covered by the rules. - either it is allowed to cruise ( chasing ) and shouldn t be punished for it, - or it is violating a rule and can be ooc punished for it ( sanction )
there s no case left out. i don t think we need to further nerf a ship when all the possible cases are already dealt with.
