Hail good Roleplayers of LOTRO, I've got a question for you all. After seeing a fair few Immersionist roleplay threads, events, movements, what-have-you, I've noticed a lot of people often have not using the AH as one of the many restrictions that go along with immersion RP. This seems odd to me as the AH is clearly not just a random mechanic. We have auction houses dedicated to the thing with auctioneers and the like, and even some NPCs actually attending the "auction" in some cases.
To me, while I don't believe the auction house was ever mentioned in the Professor's works, they clearly exist in the version of the LOTR universe that Turbine has put forth. Therefore not using them seems to be merely a handicap just for the sake of itself.
Am I missing something here? Is it in fact a massively lore-breaking problem that I've managed to miss? Any response would be most welcome on the matter.
