Unwillingly

So? If they'd be sold by someone running into a city or through a shop in a city, it would have the same result, with no additional RP either. Quit crying about it... 

Besides that: No of these Books mentioned actually contain valuable information... "How to treat Vampire wound" lmao, that's really not a big deal.

Lae we talked about this in game I cba to talk about it again when u just keep saying "so? so?" to everything I say

selling items in game, in person, brings the potential for RP even if none happens. RP should happen. the auction house brings zero potential for RP or interaction. its literally impossible. even shops are better because you could sit at shops and actually know who you're buying from. people use shops to make in-game commissions. there is a difference, one is objectively more RP friendly than the other

Selling Items via the Auctionhouse brings the potential to RP. With the Book about vampires a character that isn't a vampire could learn how to deal with them (at least with the "common" type of vampires) which brings a lot more RP, then just the meagre "wanna buy"-RP... so no, the AH brings a lot of RP indirectly ;)
