I tested on FFCraft, if i can get to 460ish craftmanship (and I can full melding on my Artisan Body) I can drop Ingenuity 2 and still mantain the 5 progress step; without the full meld at my current stats i need to put in another progress step (see this ttp://www.ffxivcrafter.com/crafting.php?step=simulator&guid=cbcBS and this http://link.ffxivcrafter.com/?id=cbcCn, I'm assuming to start at 0 quality for these simulations.)
