sorry forgot to copy the BB, Cv & SS changes over from my draft :D.
The choice is something I was looking at over the last few weeks but couldn't get it right until I looked at it again this evening.
The Battleships are now limited back to 7.
The Aircraft Carriers reduced to 5.
Submarines stay at 4 maximum(2 ss3 max)
this would allow either a CV/BB line up without subs 7/5 or include submarines and take away Battleships and CVs, this opens up the door for better tactics with ship tiers that are already quite balanced.
In hand with same ship restrictions and nation restriction this should help keep it balanced.
Remember you can not have two submarines of the same nation which also stops any op lineup.
sorry for the late update, I had to leave and go out which I was not planning on doing.
Regards,
