All ranks fire can be OP - I recommend only Sharpshooters have it.
Nah, They use Western-styled Sailing Ships; and they were enthusiastic in having the newest steam ships - there are like a dozen more steamships and an Ironclad used in the time that aren't represented in the game.
In the end, Lets just say the already existing ships in-game represents those too.
Too limiting. There is no telling that if the war escalates, The Domains will commision more ships with similar specifications, if not from the same class.
