your first point: If I want to get rid of bounties, I buy a sidewinder and let a station blow me up. So, no problem here.
your 2nd point: Whoosh, well, how many situations would that really be? And is it asured that the last shot hits your friend and it's not the one of the NPC etc.? This is not really a situation that has to be taken into consideration.
Yep so whats the point of doing it? Why code and do all that work in order to change nothing and give an advantage Solo mode. Mission synergy and long distance free travel.
Your rebuttal for my first point should never be possible and is broken. If you are a criminal and are committing crimes as such a level that you feel the need to duck out of your bounties, then this should not be possible. As soon as you commit a crime in your ship the rebuy cost of that ship will now be part of the fines you incur. This current exploit should have never happened and I am surprised its still possible in the current game.
So if you die because you were killing noobs in your combat Corvette, then you jump into a sidewinder to get rid of the bounties, the cost of the rebuy from the corvette would be applied to rebuy cost of sidewinder. You can either choose to pay it all or if you cant afford it, then you lost it. Then to combat the fact that you would be most definitely would transfer all of your stored modules to your hold before you did the rebuy trick, then the code would need to remove the stored modules that match the modules in the ship when you committed the crime if you cant afford to rebuy the ship.
20k ly outside of the bubble not worrying about the scans and you just want to go back to the bubble. Have your friend blow you away and boom back in the Bubble with a tiny rebuy. There are many other ways.
Feeling too lazy to fly back to the station to rearm and repair from a CZ turn off crimes committed against me and have your friend kill you.
I provided 2 and now 3 methods of possible exploits. I could add many more but all of them have to do with long range travel and or ducking the cost of being a criminal.
