what about a 1v1 situation or something then. if you tag a player with a bounty then no one else can attack him/her maybe, so it kinda becomes a duel with something at stake.. or players reported for bounties appear on a notice quest board or summit and you accept them all or summit, when you see the player in your quest log when out and about then its first come first served on collecting the bounty? surely there could be a way.
I dunno, just think this would liven things up a bit somehow and encourage search n destroy play or yea making a name for yourself as a bad ass on a crusade or a knobend who likes to show off ;p either way brings back bragging rights of somekind.
I remember a while back I used to look up to certain players on my realm for being awesome at pvp and they had a lil following going etc lol.. that's all gone now, no one stands out anymore
plus, who wouldn't mind a "Bounty Hunter" title above there head or something ;p
