Why do we not have the ability to speak to the quest NPC and select "Replay quest"?
It does not need to give a reward as we have already claimed it, we just need to be able to re run some of this games AWESOME content and stories and hear some of our favourite quests once more, I miss Cinder Tail, "The Frozen Man" on Bleak rock, Rilis illegitimate offspring in Auridon.
Not only would it be an expansion in content, but it would also Actually allow you to run this "Multiplayer game" with other players, and not dissapear into another instance or have to maintain a spreadsheet of characters just to keep track of who is questing with what friend.
We are long overdue a feature for replayability
