Feedback:User/Mist890718/WvW Bounty-system

My idea is that if you want, you can place a bounty on a enemy player in WvW. You talk to a NPC that first ask who you wish to put a bounty on, then what reward you want to give the player who gets the job done. The reward can be anything from money, gear to general items. When a person kills someone with a bounty the person drops a tag of some sorts that you deliver to the bounty NPC for your reward.
