I would like the option for terrain builders to have a 5" shore battery option to the 8" shore battery as standard.
Currently A fleet stands off shore with an array of 5" manned and auto AA of various sizes (protecting it) and attacks a base with 37mm AA of various types.
The base may or may not have a pair of 8" manned shore batteries. I think some balance may be adjusted if a 5" shore battery (with AA/HE options) could be implemented should the terrain builder so wish. It would have the same emplacement etc except it would have a 5" gun and 5" "properties".
