We haven't talked about the Neutral Auction houses in the game for a long time -- they exist only in Winterspring, Booty Bay, and Tanaris, and pretty much have only served the purpose of trading items back and forth between the two factions (or scamming between them). But Gnomeaggedon has a new idea: why not reintroduce them to the newer cities, and create another option for people rather than having to go all the way back to the old world (and waste a hearthstone cooldown)? Not only would you bring people back to the Neutral Auction houses (they really are empty right now), but you'd bring the auction house back to the people, at a slightly higher cost.
I like it, and so does Mend Pet, though she sees a few issues: even with the higher cost, you might still get people forgetting about the normal Auction houses and then you've just switched where the problem is (not to mention that people leveling wouldn't see anyone in the big cities when they went). And Dalaran is laggy and crowded as it is -- creating another mess of characters won't help. And finally, this is a solution without a real problem: we're getting the Hearthstone cooldown lowered anyway, so it's not that big deal to go back home occasionally (or just use a bank alt). Still, the Neutral houses are just sort of sitting there. Giving us more access to them might be worth it.
