cat units

[Gerfand]

With the exepiton of naval and anfibious units, every unit in the game act like cats...
They can't touch the water, and if they touch they get damage...
I know that the Devs make this way, but back in TA you could get every unit touching the water, but they would not be able to go too deep, unless if they were amphibious...
So there a way to make them get, only a bit, underwater?
