Coming to that conclusion. It's perfectly fine for low levels, but it starts to fall apart now in the lower levels. The reason is by the time you get to the lower floors, what you get from crafting just isn't very good in comparison to the artifacts you're possibly swimming in. Smithing is definitely UP, Alchemy and Tinkering might not be. Solution is simple: more lvl 5 crafts, especially for non-main slots. These recipes can and should be hidden though.
