Honestly if you need to write more than 2 sentences to explain how it works it's less handy than a proper AH.
MW will NEVER be better than a real AH. Never ever.

Now it's working like an abandoned failed game design idea that's trying to cater to player's AH demands but as a result it's just a mess of menus.

The good thing about an AH is that everyone knew instantly how it works. Looking for zombies with stars above their heads is about as natural as poking my eye with a fork.
