If wiped vets quit and come back, they will still quickly regain supremacy because of their knowledge and feel for the game. Only there will be probably be much more new blood in the game. And the vets will also have more Darkfall Gold (skilled players - unlike myself) who can master the game and reach the top (if there are skill caps, for example).
But I'm not saying a wipe is definitely good or bad. Just saying, if there is a wipe, I think this is what will happen.
