The reason D3 was never compromised is because it's largely a co-op game. From what I understand, this is basically a single player game so I guess it's only a matter of time until the compromised copy works better than the real version. --- Such is your fate.
I would give it a couple of weeks at most. That's a conservative estimate though. --- Starcraft II: Diamond solo, Master team Protoss. Warcraft III: high-level Human. Demon's Souls: SL 120 Pushed ToB build.
