downgrading aint so hard::
- you go to your wow folder
- go to the "Data" folder in your wow folder
- delete the "patch.mpq" file
- run your WoW repair tool
- when the repairtool starts, it sais somthing like : your wow is seriously damaged, blablabla <-- thats good
- when the repairtool is done, your wow is back at 2.0.0 (or so)
- you will have to patch up to 2.1.2 (or another version you like
)
- dont forget to set your realmlist again after the patching!
thats it
