It'll be a good thing if the npc help pages can be more detailed
give to npc some tasks
tasks like:
bodyguard (follows and protect you against monsters or players)
guard (just a guard of a zone against monsters or players, maybe that follows a path with waypoints too)
worker (npc that collect stone, wood, etc..etc.. in a chest)
welcomer (just an npc that talk to you and gives info)
butcher (npc that kill animals and collect food/eggs in a chest)
healer (npc that healing you)
monsters as npc
monsters that act as npc and have tasks like bodyguards or guards (awsome to have an enderdragon as my pitbull!)
