Problems:
We have long-standing logical contradiction – ironclad and later melee naval Units don’t require resources (Iron) to be built. It’s mainly because iron is limited and already used by Siege and Naval ranged Units and also by Minefields.
Therefore, to allow iron requirements for naval melee there should be another source of Iron in middle and late game. For this purpose we have 2 buildings which provide Iron resources:
Ironworks provide 2 Iron (can be built in 1 City)
Refinery +1 Coal, +1 Iron, +1 Oil (can be built in 5 Cities)
Proposal:
Ironclad and later melee naval Units require Iron resource to be built
Ironworks provide 4 Iron
Rafinery provide 2 Iron, 1 Coal, 1 Oil
Rationale: With this change we have +7 additional Iron recources from buildings - that's more than enough. I guess it's a rare situation when a player have more than 7 melee naval Units in total, cause there only a couple of them is needed for naval invasion.
Now a player can choose what to prioritize - a naval defense or a land defense against naval invasion (artillery and minefields also require Iron)
These changes solve a logical contradiction. Also Rafinery now is really worth to be built.
