The bottom line is that if you want an Auction House you should start listing real reasons it is better than a Market Ward. You see, I've listed reasons that the current system is better for the economy by make it ridiculously hard for RMT (or any player driven corporation) to run a monopoly on goods. This is good for everyone. It's a benefit to the economy where the Auction House had failed.

Auction House could be designed to "trustbust" but we already have a Market Ward.

Stop saying "I want one" and start listing explicit reasons why one would be better. You shave off 30-60 seconds of your time finding/placing an item. I get that much, but it's not a good trade off for me to just hand over the economy to RMT exploitation. Some people pointed out a laughable list of pros for AH that could all be achieved by a Market Ward system.

Why build a redundant system when the current one is capable of functioning the same way, or better overall for the economy (at the cost of a small amount of convenience)? That's what the real issue should be.

You want one isn't an argument. No one cares about that, including SE.
What does an AH provide that makes you want it and why can't the Wards facilitate that same need?
