I agree that Wizards should really use the dungeon tiles with their published adventures.
No thanks. I'm already wavering on dropping my auto-purchase of WotC published modules for quality reasons. If they started coming out with areas solely based on Dungeon Tiles it would probably push me to stop.
I'm sure you can be creative with the tiles, but it would *feel* homogenized to me if the areas were built purely of dungeon tiles.
I understand the "let the dungeon tiles inspire you" crowd and I can see the utility in some limited situations. However, that's the opposite of what I would want in a purchased adventure. If someone has a vision of an adventure they shouldn't compromise it based on the available Dungeon Tiles.
