I have never played a Diablo game, and I find these exploit and bug reports entertaining reading. If it was every stupid minor thing, then no, but an invulnerable wizard sounds neat.
P.S. I loved Torchlight and pre-ordered Torchlight 2. With my pre-order they give you a copy of T1. Anyone wants to try Torchlight, hit me up here and post your steam ID and I will friend you and send it.
