I havent wanted to craft that much because this levels your character. I really think that the crafting skills should level you at about 50% of the normal leveling speed. Any other people not crafting for this reason? To me its most important to be able to survive a battle and some of the battles in this game are pretty tough!
I'm limiting myself to 2.5 points per level... again, it's up to you to make your character the way you want to. I want my smithing to be 100 before I get to 50.
