As I mentioned in a previous post about how quickly I reached level 60, I discussed Caudecus’ Manor (CM) and how some players were farming loot and XP there. I ran it a few times to earn some money but backed out because of how much XP was being gained. It seems that ANet wasn’t cool with players farming CM or any one instance, for that matter. In a recent patch They’ve implemented a change for diminishing returns if you run an instance more than twice in a row. Personally, I didn’t see a problem with someone electing to play their game that way.
