I am looking forward to the concept of embarkment because it will make having a navy that much more important. If you are maintaining a choke point... a peninsula or a straight of land or something, you are able to hold a key piece of land like that with very few units and taking advantage of the terrain...
Now if ground units can just run into the ocean and go around such key locations, it will be important to maintain naval control of the area to prevent such actions. I imagine that you won't be able to embark on ocean and disembark back onto the land in the same turn, meaning that attempting to sail around a defended position will leave your units extremely vulnerable for one turn.
