I don't know any game where I can step into the game the first minute and immediately am able to craft the best in slot endgame items (provided I buy the materials).
I would make all basic crafting items available, but for advanced and supreme item recipes, you need to purchase them with something.
Ideas for currencies to buy recipes with:
- a new currency tied to daily/weekly quests. If you run out of your daily/weekly allotment, you can buy extra at the marketplace at a premium
- solon/hyperion/crypton, whichever is least used
