This may not be the relevant topic for what ill say, but flagship should be exclusive to pirates in my own opinion.
Every path should have its benefits over every other path that competes as a said path. Pirates have more battle skills, merchants make more money than all, shipwrighters make ships cheap and fast, as well as making good quality ships at the same time, privateers honing battle skills only a merchant can access to counter pirates to the best of abilities,
Pirate hunters to fight pirates and having similar abilities yet more abilities to counter that of a pirates abilities
Fishermen being able to profit with no trade routes and can provide for themselves. Perhaps voodoo to counter the amount of healthy “wild catch” that the fisherys recieve.
I know i am going off and am not trying to derail.
Overall the message i am delivering within this is yes, pirates should be able to have pirate only perks: ones where only pirates can get these abilities and that are worthwhile. Not gold no no...fighting capabilities! A pirate can make 2 million a day with skirmishes along with max skirmish tech if done right. Piracy was loads of fun for me, but just felt like it was missing pieces. The only real advantage was ship count for piracy. Even then, you still couldnt compete very well without the risk. I do not say lower risk, i say more advantages to piracy should linger around. Fame could be very useful if pirates (those flyig the black) could incorporate abilities based on fame count.
