in my judment, water tiles arent good enough compared with any other tile. 2 food with lighthouse is just not enough.
they definetly need an upgrade in food / production / gold
regular grassland at a river is 2 food 1 gold without any upgrade. later on with a farm and right tech / civ its 5 food and 1 gold while a lighthouse needs forever to be built just to hit 2 / 1
they worst part, if you have water tiles in your city but arent right at the ocean and cant built a lighthouse (that definetly needs to be fixed by the way; you always should be able to built a lighthouse / harbour as long as you have water tiles and a road) and its 1/1
water tiles should be (with light house) with a certain tech or another building at least 3 food 3 gold, maybe even add a hammer.
