the basis for naval warfare should not be protecting improvements on coastal tiles. thats a pretty weak justification for building unupgradeable ships, especially when a much better dual purpose defense comes into being just 4-5 discoveries away.
i cant imagine wasting the time to bombard down the AI's coast with frigates and ironclads. resources yes, the whole coast like the AI, never.
the only thing i cried for in this expansion was bringing back farms/refrigeration from CIV II. no luck on that count.
Since it causes you to invest in things you don't want to build and was time rebuilding roads it would seem to be a dang decent strategy. I do it to the AI myself now and then to cut their movement points and isolate a city I plan on invading.
