I spent a LOT of time on crafting, but then found out recently that Yoshi is purposely making the crafted gear not as good as dungeon drops... for this reason and this reason only I have put it on hold while I do end-game content and gear up.
I started crafting to make my own armor and weapons... and so the crafting jobs I leveled to 50 were Armorer, Goldsmith, Leatherworker, and Carpenter.
I wish they would make crafting a little more viable for end-game... as of right now it's basically just a mini-game, which is really sad since it's such a good crafting system. It's fun to level, fun to do, the mechanics of it are very engaging.... but all of that is for nothing if you can't even sell your items you crafted.
I will gladly jump back into it if Yoshi changes this to make crafting more useful...
Right now my 50 Miner is more useful then any of my 50 crafting jobs, because I can go find treasure maps in the level 50 nodes that I can sell or use...
