Heres my pirate types i have encountered over the past yr.
Dirt bag- a pirate who rolls up on a ship and fires without a word, toxic talk and an all around doucer. Hey Joe Neate or a rare employee may be on the other boat, you wouldnt want to leave a bad taste in there mouth would ya? ( avoid)
Chicken dumper-they avoid all boats and pirates at all cost, scuttling at the first sign on danger, rarely high level (help them)
Lazymen- a pirate who joins the crew and does nothing, good at the concertina, not much else, waiting for you to do everything. (Avoid)
Time wasters- dropping ancor while full bellow, shooting cannon balls in to the sea. Drinking grog to throw in your face chasing you for no reasons(Avoid)
The Richie-hardworking Rich pirate, a joy to have on your crew( add)
The Royal- a good all around pirate knows all factions on the game, a hard worker( add them)
The Legend- few steps above Royal, the true pirate legend, showing new players the ropes, finds treasures quickly, and always a kind word. Great pvper.The best of the best( add them if possible, they rarely add because they are so good)
Just my opinions on pirates i have played with. Im sure you have more :) Which type of pirate are you?
