Acquatic trade routes and splash damage fortress

I thought these two new ideas

Water trade routes, where you have to connect two ports with a trade ship, just like the normal trade, but with boats instead of caravans, it would make water maps way better

Fortresses with splash damage. It would be interesting to have defensive buildings equipped with catapults, capable of doing splash damage and being really effective in defense, maybe even with fire damage

Water trade = Could be interesting, but nothing that I would me excited about. Takes too much away from land.

Fortress splash damage = before last patch, maybe. In the current state, please don’t!! lol
