Guild Wars 2

Something like this should be added for something extra to do at end game, example “Track down the elusive monster grizzle bear that roams in a certain area” and give that monster an unique weapon or armor skin for killing it, also since it is for end game, make them very challenging. This would be a very fun thing to do, as i sit in lions arch alot with nothing to really do, and i think this would make a very nice time sink. Make the spawns random from the same type of mobs around in that area.

Monster Hunter ?

No, something like what FFXI and wow does, but rewards unique weapon and armor skins.
