It just seems like alot of work with no real need at the moment. Warp, Kafra and Tool-Dealers implemented in every town by their warp-points? Thats like, 75 NPC's implemented alone, without having to fix the Warper NPC. There is a guild-storage NPC located in Forsaken City. After a while of using the various NPC's I know I, and others tend to memorise the co-ordinates of their locations. So there's no real-need, in my opinion, to implement loads more NPC's where most will remain unused.
Just my opinion~
