Crafting, robust and as much depth as possible. Let me break items down and improve my current equipment. Look at Dragon's Dogma or better Vagrant Story. I highly dout we'd get crafting that is so important to combat but I'd love to see something like Vagrant Story done. Just read the paragraph on how it works I LOVE it. As for Dragon's Dogma you can only enhance your loot with materials you've found in the world which is also fine with me.
