I would love to see a bounty system of some kind here on Badlands. If you make a kill and are marked in some way, a flag or and effect shows up on that specific character that made the kill. If a character has that mark, be it a flag or some other effect, any other character is free to pk that specific character to claim the bounty, effy kill or not. Also this could be a marker of a different sort, one that marks how many kills you have in a row with out getting killed yourself, the flag or effect could change colours from one kill to five to ten, etc.
It would benefit pvp on the server and make it fun to hunt down a character to take his marker away from him or how long you can hold onto a marker for ten kills or more.
