Shai, I'm afraid I'll have to respectfully disagree with you here. And this is speaking as a someone who thinks of herself as a crafter / gatherer first and foremost.
The market system should NOT cater to crafters and gatherers first, imho. It should serve all players equally, whether supplier or consumers, buyers or sellers. Setting up crafters and gatherers to have fun at the expense of combat classes won't lead to a fun game.
Let me take a stab at a Matsui-san style mission statement for the market system (which could include the current market wards, a simplified menu-driven interface, or a true bidding-style auction house, or whatever crazy scheme gets cooked up).
The goal of the market system is to provide tools to:- Efficiently match buyers and sellers
- Allow mutually satisfactory prices to be quickly determined
- Minimize the impact of market manipulation forces
