I agree it's way too frequent, which is not only annoying but also makes NPCs less believable as "real" people. I mean, sure, they are always more or less standing in the same spot, they always more or less say the same thing when you chat with them, etc. All things that are unrealistic for real people to do in the first place, but for example hearing that one legionary say "Where is my pepper? Did it sprout legs and run away?" every ten seconds makes me think of her as an alzheimers patient. Reducing the frequency of this chatter won't [i]fix[/i] this, but it'll help greatly. I'd say once per minute max, ideally once every two minutes.
