Port Battles: I know the devs are working on a new port system, we will see if it is better. However, the current game mechanics could've been easily fixed by allow only 1 flag to be pulled at time.
Since this is still Alpha, things can change.
Port Battles: Current System
Multiple Flags can be bought (No Limit).
Capture a Port (48 hr cool down until available).
Defense (Must defend the same ports every night even if you defended and won).
Towers are too easy to take.
Port Battle: Suggestion (if new system fails)
​Only 1 Flag can be pulled by a nation at a time. (Once the port is captured or defended another flag can be pulled)This will eliminate false flag buying and in most cases empty port battles and at the same time create big Port Battles. (I've been in a few and they are so much fun 25 v 25 an not 12 v 0)
Capture or Defense of a Port has the same 48 hr cool down before the flag can be available for that port.The Defense of a Port should reward the defenders with the 48 hr cool down, same as capturing one does.
I understand that new system is coming. I hope it creates more PvP, we shall see. (PvP2 player)
Ship Durability (Historical Accuracy)
Make every ship 1 durability, I don't believe the Constitution could sink 4 times before the US would lose "Old Ironside", then we would really see who are PvPers and who are not. Too many times I've seen nations rollout 2nd Rates or less to Regionals because of the durability issue.This generates more business for trade and crafting players to help supply their nation and contribute to the game.
Make all upgrades in the game available to craft. This will ease the minds of losing upgrades on their ships.
I may have been repeating some of the same things discussed over and over, hopefully not.
