I realized, that at a certain point, the AI runs out of resources and they stop spamming elite pirate ships at you. You can peacefully train your men and just take out the 2 forts and the 3 town centers.
Are other legendary quests like this too?
Guys, Is it possible that you can spend real money for in game gold (a pay to win situation)?
I don't have too much patience to gain gold and get my gear back ever since the shutdown.
