Redo the Crafting system.

[Silverbane]

... the best of both worlds would be to keep the math mini-game but change the stats on finished products. Change them from fixed values to an RNG range.
The goal would always be to get 100% quality but that will no guarantee an optimal outcome. And, due to RNG, a lower quality out come could still produce a weapon of the same quality as the 100% quality craft.

So, crafted items might be like pink Diadem drops: a fixed iLvl (that ought to be higher for HQ, frankly) and some randomness in the stats (perhaps only in the secondary stats).

Sounds fun, and I suspect most of the mechanisms are already coded.
