I suggest a new item be created. A PVP Blackbox. These would be size 0 and stack-able, equip-able, but not unequip-able.

Bought and sold at all ai stations for 20m/10m

The PVP Blackbox will only drop if a player with one equipped kills another player whom has one equipped.

When the player is killed in PVP and both players have one equiped, the killed player will drop 1 PVP BlackBox, and one size 5000 black box that will remain in place for 48 hours that will say "Player X was Pwned by player Y here!" Alternatively when the PVP box drops a shout in all chat or event chat or even an all new chat named pvp chat could happen. Like saying "Player X was pwned by player Y in galaxy Z".

The idea is kinda like in Medieval Total War II when a battle happened a historical marker was left the the grid.

TLDR 2/1 credit incentive and alert everyone you pwned someone in pvp

I cant find it, but i suggested a while ago that a pvp leader board be added to the game. Basically a stat sheet that keeps track of everyone you have killed and who has killed you. You could see it in your avatar thing or something. Also a pvp leaderboard giving 1 point for a kill -1 for a death, simple. While its not much, i grantee players will be pvping a lot more just to get on top of that pvp leader board.
