What is wrong with crafting being a part of the end-game?

I don't get it. Why can't a key-material drop from a boss and require you to find a crafter to make it for you, like request melding? It feels weird that they went through all the trouble of making crafting an actual thing and then only let them make social or vanity things.

Don't think it was a good idea.
It could be read as adding item (key-material drop) that crafters cannot obtain, must relay on Battle class. ^^;
