Seriously, these guys are AWESOME! Particularly the elephants!
All the benefits of an NPC helping you carry stuff, and none of the side effects of them wondering off with your loot!
I reckon I'll have the world paved in 30 days with these fellows helping!
Though once I complete xadesburg, I think I'll settle down for an intensive training course, popping out occationally to feed eat NPC from my farm when they're hungry, thus spamming my karma to orgasmic levels!!!
The "several come and go" message preceding that actually covers movement of people prior to and after particular events like slayings. It's hard to improve the sort of event scan of that without retooling on already monster complex movement notifications..
