Pirates of the Burning Sea understand that. The developers have been making adjustment to their open sea engagement rules to find the right balance to make a memorable encounter.
While the team initially restricted confrontations so that ganking by player mob couldn't happen, the devs admit that the end result wasn't what they had hoped: "That adjustment went too far, and the fights since have by and large been less dynamic."
So to bring back some of the unpredictability in encounters without making it a gankfest, the devs will be tweaking engagements so that at maximum they can only be two-on-one fights. They also vowed to keep an eye on these fights going forward, particularly in regard to the reinforcement timers.
