Water based troops for unused part of map?

I think new water based troops and a new blue currency of some sort should be integrated into the unused water section of the map. A new hero of water could also be available.... Poseidon style

Maybe they introduce a really strong water troop, but it can only be deployed on the water and it has to swim to your base? That way, the defender knows that this new strong troop will only come from one direction of the map and they can build a base accordingly.

Well, then we'd have a game too similar to Boom Beach. So, I don't see this happening, sorry.

I can actually see a whole new area similar to the Builder Base. and the addition of aquatic warfare actually sounds really cool. maybe it could be like a dock or an island or just an extension of what we have already.
