I disagree. No amount of rules could make crafting interesting. It's just not why I play the game.
Same reason I have tried, and gotten bored quickly with the crafting rules in Everquest, Everquest 2, Dark Age of Camelot, Neverwinter Nights, Neverwinter Nights 2, World of Warcraft, and City of Heroes. Most of them spent a lot of time to try and make crafting fun. Some even made patches in order to completely overhaul crafting and I played them before AND after the overhaul.
I don't want to be the guy who makes stuff for other people. I may be the glory hog, but I want to be the hero everyone cheers to for saving their lives, not the guy in the back of the room handing out drinks. It's not about the mechanics, it's about the prestige that goes with it.
