I don't have a problem with the gating aspect, it's just the way they are doing it. An auction house? I mean they could've came up with an intriguing questline or some kind of grind (similar to the legendary questline), something that takes some effort but is also not as mundane as camping the black market auction house to make sure you are the last bid, and thats even if you have enough money to keep up a bidding war. It's disappointing seeing the dev's take this route.
