Hey Drygord,
this sounds like an interesting twist to a crafting mechanic. Especially as I havent really seen something like it yet.
Utilising this system I believe would make for an awesome feel of authenticity and also allow stronger tiered weapons without resorting to high-fantasy adamantium light sabers etc.
True!
I have to say though, that there wont be a crafting system. At least not in the launch version of the game. What I would like to do, is use some of these patterns for a distinctive look on certain legendary or named weapons if I find the time.
Cheers!
