Right now, Myoko (with the spare Nachi AI) is AA build, ARP Nachi is spotting/scout build (though not as much as I wish it could be, WG won't let us use the special upgrade modules on ARP ships, so that Hydro booster ended up on Hipper instead), ARP Ashigara is secondary build because reasons, ARP Myoko is a hybrid guns/AA setup, ARP Haguro is all about the fires. I try to run a different build on my duplicate ships, which is easier on the cruisers than the BBs. I have yet to assign Iona or Gunzo to a ship (I don't even have a good reason why) although I've used Iona on one or two premium BBs for a short time. As I like to joke, A significant portion of my fleet runs on Fleet of Fog AI's. Heck I have 5 Kongo class battlecruisers, 5 Myoko class heavy cruisers, and two Takao class heavy cruisers, as well as two of nearly every one of the captains for them (except Iona, Chihaya Gunzo, Myoko (missed earning her the first time around, got her on the second), and the Yotarou version of Kirishima). I have destroyed every tier IJN BB with my German BBs over the years. I am a die hard German BB player, as they fit my play style better. I am really only interested in getting the Yamato. I sold the other three Kongo class ships and Myoko's sister ship and even though I have picked up the HSF Graf for grinding coins and commander xp, I began to grind the IJN BB line. Then I began to take the Kongo out and as I studied her online and in the forums, watched videos and got used to her, I began to win battles and make money with her, to the point that she became my main grinding boat for over seven or eight months. They stayed parked in my port for almost a year, until WG provided an english speaking commander. I took one out and was instantly turned off by the shrill teenage female voice barking messages in Japanese. I had never heard of or watched the shows. I did not even remember how I won the ARP ships (Kongo plus her three sister ships, the Myoko and her sister ship).
