After visiting the test server and seeing some of the awesome loot drops, I'd like to know is crafting ever going to have the ability to modify the stats on these items?
I'm not sure how KI would do that, although it is an interesting idea.
Usually crafting is about creating a brand new item from scratch, with preset ingredients.
Making one of the ingredients a preexisting item, and a variable item, might be doable, but I suspect it would be tricky to code in without affecting overall gameplay.
