Pirate-Trader or
Trader-Pirate
Lets say you Qualify for this special designation. It entitles you to benefits of both pirate and trader.
The requirements are negotiable. Lets say 25 ships or less. Achieve blank amount in trade over blank amount of time. Achieve plunder based on number of attacks plus gold/fame gained in specific time frame. And its relative to your experience...IE..the newer you are the easier the requirements. Combine two to get score. Could be calculated weekly or monthly. I wanted to be more specific but am open to ideas first. The main idea being to combine benefits of trade and piracy ( most do not know piracy) for the most die hard pirate/traders that occupy the seven seas. Please feel free to expand. All ideas are welcome

Yeah maybe there could be some reward for the most combined weekly profit. where the two numbers would be multiplied. Like if you made 10 million a week in plunder and 10 million in trade your total score would be 100. But then again there are some big trader's out there so a 2 million pirating minimum would work.
