May I also suggest for open port to only be open for selected nations.and or clans within a nation. Also port open for all in selected timeframe.
I think the idea with higher drop of exceptional ship is for you to transport the mod not the ship due to it being purple or gold.
I don't like the increase of exceptional ship, I would rather have shipyard on capturable ports, open the possibility to get the IA trims. (not by region, just give access to the remaining trim)
I hereby suggest the introduction of a black-market mechanic and marketplace:
ports dropping precious resource only drops 90% of it in the drop port. 10% is released on nearby ports (within 50k).
resource restricted to clan only
70% to clan
30% to blackmarket
resources restricted to selected nations and clans
20% to clan
60% to shop
20% to blackmarket
20% to clan
70% to shop
10% to blackmarket
marketplace, would be a feature working as clan market in some selected towns. in the case of resource restricted to clan only, the clan would have to make a weekly auction opened either to own nation or selected nation clans for 50% of their weekly selected resource income with a price min max between q1 and q4. Failure to sell in the auction would result in the release of 50% of the resource into the blackmarket and reduction of drop-quantity by 30% due to surplus and increased port management fees by 20% due to storage.
marketplace would also be a place where clans of all nations can do auctions for resources, ships, missions (escort trading player, screen etc), and more. available in a few ports over the map. Resources sold in marketplace wouldn't have to be in the auction port, but should mention where pickup location is.
Blackmarket would give meaning to surrounding ports dropping precious good and marketplace would increase exchange of resources and services at clan level.
I know devs will say no, because the game is not in development anymore but in tweaking phase, and this is a lot of development. but there is so much to change in this game to make it real unique and great, it may be worth going back to development phase.
Also ports in the south need precious resources and improved trading possibilities. Right now most precious woods for instance are in the eastern safezones or in shallows in the north. there is literally nothing west and south.
Ideally ports consumption and drop should change overtime based on the surrounding owning nations.
