A more efficient approach towards purchasing equipment from an NPS

At the moment, it seems a little disorganized how the NPCs are setup to sell items. Perhaps instead have an NPC from each class sell a weapon specifically from low level to high level. This would be a more uniform approach, rather then checking out every NPC from Elle, to Ozz for weapons and such. Elle can be left to sell strictly potions and mana. The town has to be remodeled, its not very practical the way it is at the moment, perhaps this will be seen when the Guild and Auction House becomes implemented.
