What if aquarion turned the land in captured villages into strictly water?

Aquarion troops get a movement boost in the water, but the villages contain land and land resources. This isn’t ideal for a water tribe. What if when you captured a village, it turned the land into water. That way you aren’t restricted by land that 9 times out of 10 has no use because the resources are so sporadic in a single village.

The water surrounding a village could contain water resources - fish, seaweed, coral reefs, literally anything water related and the resources in the tech tree could be changed to fit the water elements.

I think this would promote water movement for aquarion since only a few troops get this bonus. Similarly to how polaris freezes land to promote movement for their troops.
