Only two things need to be fixed with respect to CV's:
1) They can still get too close to shore. If you can cap an enemy field with your CV ack, then it is too close to shore.
2) Towns and fields need to flash if being shelled by 5 inch and 8 inch guns regardless if there are uppers or not. You think someone would sound the alarm with all stuff blowing up.
1) The thing is, this argument will still remain as bombardment task groups (which I REALLY WISH would be added) will still be within a couple of miles from shore, and THEIR ack will contribute to things. So if anything, get use to it as I believe the ack from a bombardment group may in fact, be heavier. If you mean a CV in general, I whole heartily agree. I don't recall of any CV's of any kind being so close to an enemy shore line as ours do.
2) I FULLY agree with this. If it get's shelled, it should flash. It does not make sense that something wouldn't flash when being shelled by anything. The same should hold true for TG's as well. If a shore battery opens fire on the TG, it should flash. As for GV's, I honestly do not remember if a GV upping to shell a CV that's off shore, will cause it to flash. I would think so, but just can't remember.
