I dont get that. How would they discern that a fleet is in the sea zone without actually spotting it, and thus pinpointing its location?
Well, I guess intel and radio listening would be the only one. Also if it's spotted by aircraft from a capital ship, it might mean the fleets aren't close enough yet. It would be nice if cruisers were the best patrol boats now, as they were the smallest type of ship to have planes, and search radar wasn't very long ranged.
The new management system sounds cool though, can't wait!
BTW, I wonder if we can finally get properly priced destroyers? Since they are in flotillas, shouldn't they be generally more expensive than cruisers?
