Please don't bring naval imbalance to Land based maps

Sorry for the rant post but I have faced the issues too much and can’t hold it back.

I know naval balance is completely none-existent atm, but what’s worse is seeing people abuse them in river based maps. Big Warship like Hulk and Galleass, backed by dock auto heal is completely unbeatable for land units and some civs with weak water units. I have met many people who use these OP ships in river based maps to defend river crossing and even deny the opposite site from reaching the Neutral trade post like the Mongolian height map.

Please just ban those big Warship in river maps, it’s also ridiculous to see ocean going ships in river to begin with.
