There *is* a way to defend amphibious city razing, by the way. Everyone's pretty creative, so I'm sure you can come up with it.
And if you can't, then for once in our lifetime we can use a civ IV game tip: on water maps, powerful navies are not optional.
Answer: use your own amphibious raid or sink ships. It might be true that you can't garrison and actually defend all of the coastal cities, but if it's come to that you screwed up and deserved the damage. Someone in those games won, correct? It was decided by each team's actions, right?
I am very much against arbitrary bans of actions that are allowed in the game outright. Amphibious attacks are heavily penalized in most cases, and yet remain one of the FEW ways in the entire game where the game isn't heavily biased against a human attacker in a 1 on 1. No walls far less concern over collateral initiative (but not none!), high priority on heavy scouting.
If amphibious raze is banned we might as well start banning more wonders, ban state property, ban bureaucracy, ban elephants, ban catapults. Why not?
Nobody said to ban anything!
The point was that Vikings have an advantage in sea based maps, because amphibious attacks are so hard to defend anyway, let alone when the opponent has 2 move or even 3 move advantage navy.
Tip: A navigation2 galleon with circumnavigation is 7 move unit. In 2 turns (move last attack first) that is 14 tiles...you have lost all your coastal cities before you know anything is comming!
