It could be, but I remember on my first craft that I lacked one ingredient which didn't tick off.

Perhaps 51s don't work I'll need to complete all other ingredients first though.

Also, for the 55 gear, do you actually need recipes to make them? I've seen a few in CS that say "Level 55 Weapon of Blah". So their recipes are the rare drop from bosses maybe? (since I've seen one drop with the same format "Level 55 Wand of Blah".
