Underwater Province Defense?

[Poopsi]

When I was ten I was given a book on celtic mythology and another one on Egyptian, so I´m familiar with some general stories (such as the Fomorians, through I didnt know about the watery dead theme, or Long-Arm Lugh) and picked other stuff elsewhere. But I´m not too buff on those either.


My personal take: remove water nation´s surface PD capabilities. After all, they already have an advantage over their surface counterparts by having amphibious units, so they can still attack with minimal risk of reprisals.
