possible solution for champ farmers
Edge of the Mists is already like this. The problem with doing this with WvW is that people who play WvW don’t want to wait in queue for farmers to get done farming. It might not be a problem in lower tier servers, but I bet it would be a problem in tier 1…and maybe tier 2 as well.
There is no need put trivial, repetitive content into the game with high reward just to satisfy farmers. The farmers may vociferously ask for this but it is just as bad design in WvW as PvE.
