"Making boots non-slippery" counts for me as "enhancing existing armours".

As for crafting: Who wants +1 on "Lucky Charm" to find even more useless EQ when they can have two or three things on the boots that actually give something to the char?

What I also find odd that you cannot craft entire tiers of certain items, as helmets (yes, I know about the cooking pot and the pumkin), or bracers. Or did we just not find the proper recepie for that?

I think the amount of things you can craft is perfectly fine, I just have a few additions. You should be able to make "cloth stripes" from "Folded Shirt" + "Knife", but the issue is that what you craft as armours simply cannot compete even with mediocre magical items you find, simply due to the special features those other items come with.
