You have enemies? Good, that means you stood up for something.
There's a million and one WoW hacks out there, problem is you can't use them without getting instantly banned from retail servers. What is it that you want to do anyways? I mean, there's a cool mod to make your character model look like anything you want, go look up "tMorph".
In terms of "hacks", there's plenty, you can fly, teleport places, etc. If you use them on a retail server you'll get banned instantly though, they would only work on SOME private servers.
