I dislike Karma systems and such as they can most often easily exploited.
But what about Title additions based on your actions and interactions with other players?
So lets say, if you sailed 3 hours ingame time without to harm any other ship and player, no matter if you had to defend yourself or attacked. Just not a single hit to another ship and player you get the addition of "placid" to your title.
placid Legend of...
placid Seafarer of the Shores of Gold.
placid legendary Krakenhunter etc....
if you manage to do this 6hrs ingame time: calm...
9hrs - tranquil
12hrs - friendly
15hrs - bloodless
18hrs - peacefull
Vice versa you can have additions to your title if you are constantly a threat to other players.
restless, unruly, burdensome, dangerous, bloodthirsty...
And this just as an option and not constraint!
People who dont want to show this, dont need to and people who want other to know before they can find it out by themself can add it to their title and it changes regarding your behaviour ingame and time related.
If someone who is peacefull attacks another player he instantly becomes restelss.
If someone who is bloodthirsty miss to attack more players he becomes dangerous.
So its different for both directions how they expire.
Beeing someone who is friendly and break this rule instantly looses all of his "reputation".
But someone who is bloodthirsty would only loose one grade of it title addition and its not so easy to become neutral or tranquil again.
If i have overseen a flaw in this idea, please tell me.
