> BB Double Attack (Anti-Installation-type) equipment setup

Actually I would recommend just ignore it even though it is Land Base Boss, if the combined fleet is used. Use AP shell for BB and save the precious Type 3 shell for the second fleet. There are two reasons for it:

1. First fleet doesn't enter yasen, which BB are usually in. 2. AP shell have buff too during daytime battle.
