Sounds to me like unused content which should be updated to have, you know, use. Even something simple like giving a sizable XP bonus for killing mobs in the area. Isn't that what Fields of Valor is supposed to be? So I can only assume that if an area is unused, it's because the XP rewarded isn't enough. So wouldn't the sensible thing to do be to increase the XP reward?
Kind of sad to think how the developers still flounder with that game's balance. ****, I will retract my earlier statement if for no other reason than having the old designers on board would spell the doom of any MMO.
