Please put this way down in your priority list. I accidentally got the "French Rules the Waves" script going and we decided to go forward with it since we are most likely going to restart after this patch.
So, NM drops down and France gets a bigger fleet, got that. But it's a not a very good "what if" because France doesn't have enough admirals to manage even 1/2 of the bigger fleet making the extra ships pretty much useless with the -35% modifier.
With the cost associated with it, you need to provide a few more admirals so they can manage the extra ships otherwise it's a waste.
