It would be good to know what the clear line is between Craftsmanship vs. Magic Craftsmanship (and even Main Hand vs. Off hand). I thought about doing tests myself, but am not even sure if they are finished with modifications to the crafting system (as long as I see 'dated' recipes, I think they are not done).

I was secretly hoping they would get rid of Magic Crafstmanship and have only Craftsmanship, or even get rid of Off Hand and have only main hand. But the new Militia equipment they release is Off Hand tools with Magic Craftsmanship stats, which suggests both aspects are here to stay.

Given the 'randomization' of results, I really think it would be fair for us to be told:
Recipes that have 'this' in it, are magical, the rest are not.
Recipes that have 'this' in it, are best used with off hand tool, the rest are not.

So there is no doubt on what we are doing so we can focus on just doing it well ^.^;
