Though this game has a few shortcomings, the quests for the most part are well written and fun to do. Still this being an MMO and all, I'm feeling there is a huge lack of other activities to do other than fighting or gathering mats. With that in mind I've thought of a few things I would really like being implemented to bring variety and more interaction between players.
One I think I've already seen it mentioned by the devs would be horse racing events. Closed tracks with obstacles that you need to jump over so that to win the race skill would be required. And create different events for ranges of horse levels.
Another would be fishing contests, now fishing is kinda useless but it's there, so why not giving it some usefulness?
My third and most elaborate idea would be to create a most wanted ranking when the justice system gets implemented and that you could receive quests to kill a certain player that belongs to that most wanted list. To make it a difficult as possible to exploit this activity, you could only do 3 of these types of quests each day. Other rules to make this work is that there would not be a quest pin on top of your target as that would make it too easy to finish the quest. To know where your target is you'd see a circle on the map for a large enough area where he could be located, and when you where like 100 meters near him a warning message would pop up for you and your target so each one would be aware of an eminent confrontation could happen. And to stop a player from simply disappearing by teleporting himself when he received a message warning about the proximity of one of his bounty hunters, teletransportation would be blocked out when you were less than 100 meters afar from your target. Each "outlaw" could be chased by max 10 different persons and at the time the quest was chosen the game would pick a target that is close to your range level. And to give it a good immersive feeling this quests would be given by the dark brotherhood guild (when this gets implemented

). Like it was a rich client that made a contract with the brotherhood to eliminate a person that he's afraid for his life. And to pinpoint the target the player could ask at the brotherhood guild some directions and the response would direct you to the zone where the target was currently on. Oh how would I love to see this bounty hunting stuff seeing it's daylight here at ESO
