Early on, it was really good to supplement. Like level 12 I had so many gear gaps, I crafted a bow/leather armor/2h axe/staff. I then used Joshua's Spice on the 2h axe, bowstring and spyglass on bow, dipped all in elemental forge/grindwheel, used some elemental orbs on them...

I am now level 16. The 2h axe is still stronger damage (by good amounts) then even level 15-16 legendarys. The bow lasted a level or two and got replaced, which is usually how it goes. Armors tend to get replaced even quicker, since 1 level makes the different in armor, but also going from like +1 dex to +2 dex ect ect.

So yah, its kind of supplemental gear, but I use the Crafting Overhaul which makes it a lot more viable. It just fills gaps in level appropriate armor.
