What if you kill an enemy player on your ship but, instead of going to the ferry, they go to your brig. They can only be set free by the capturing crew, your ship sinking or their own crew getting down to the brig and holding "X" or "Y" or what ever PC players press to let them out.
This creates more risk and forces better tactics.
What do you people think?
So just to break it down
Anyone you kill on your ship is captured. They can only get out by being released, or if your boat sinks or they are freed by a their crew.
You board their ship and are captured. You can't go free until they let you out, or their boat sinks or you are freed by a crew mate.
If you are on a Sloop and decide to board. (Since a sloop is hard mode) you have great risk, especially alone... no one would normally attempt to board with a voyage down while alone. (Unless you're nuts)
You can't be captured on your own ship
Killing players anywhere else will not result in brigging*
I purposely didn't include a timer because I wanted to force strategy.
If you have Galleon vs. Galleon you have to think is it worth attempting to board the Galleon to free your crewmate or do you sink the Galleon to free your crewmate?
If you choose to PVP on a Sloop and tend to board other ships. This creates greater risk for you as well as possible repercussions, as the ship's you decimated face repercussions (lost treasure).
Currently there are no repercussions for PvP'ers, because the players can just keep coming and coming and coming with no loss to them.
