I would still like to see CV's have a resupply convoy much like the trucks used to be that leave from their port and steam towards the CV to provide it with fuel, ammo, food, etc... This way you can bomb the supply convoys to help keep CV from repairing as fast, and also track CV movements by following the supply convoys. Arm them similar to trains, no puffy though. It'd also give things for PT's to do besides spam spawn when a CV is in the spawn, or get killed before getting within 5K of the CV by manned guns.
