its a bit strange when you come up with a roleplay argument like "battleships need fightercover anyway" when we are discussing a rule that is made for gameplay issues and not roleplay.
this rule protects smaller ships, allthough its not plausible in terms of roleplay. - the sight of a battleship chasing a fighter isn t really a realistic one - but things shouldn t be stretched too far. - sitting at 4k recharging cause the SN can shoot that far is loopholing.
