I think the market wards are extremely tedious compared to standard AH in MMOs like WoW and LOTRO. You need to constantly run between your retainers and the item counter to check price and set prices in your bazaar. Checking prices is also a multi step process, you have to first locate what category it should be under, than scroll to find your item (no filter or search), and that's not even enough, you have to click to list the prices in another window.

I'd much rather have a centralized interface where I can click one of my items, list matching items already on sale and then set my price accordingly.

Browsing is a little confusing for beginners too. When all I care is upgrading gear for an ARC, it's not obvious where I should look. I'd rather just be able to look up items by their names, or stats or class.
