Personally, I like the wards system now.

It's not hard to track things down when I need them.
The prices are fair in the sense it's what the seller thinks the item is worth (and not just based on what the average it's been sold for in the past).

My only real wish is that sometime in the future there's a sort feature that focuses on major stats like DEF or ATT. It's hard to find out what is best overall currently because you have to glance at every piece of gear in that ward type.

Oh, and maybe link the wards from all three cities. >.> Eventually.
