their are too things that i hate about the navel system in HOI first is how all of a sudden half of your fleet will dissipear in a fairly light engagment where you drastically outnumber your enemy though i don't know what could be done about this.
the second problem would be more easly solved this has to do with when you repair your ships i agree with making it take time to repair them but its how this is carrided out that pisses me off. for example lets say that you have a large naval force and it has been damamged so you repair it so the ships are transfered to your build/ deployment que this is all fine and dandy but when they are finished being repaired you have to deploy them all
