I had actually played a private server for classic about a year before they announced the first run of WoW classic. It wasn't all that hard to set up and ran flawlessly. I'd made it all the way to 60 and done most of the dungeons and a handful of the more casual raids. I think Naxx was still not available, but I never got that far. I couldn't see myself paying for the privilege to play an altered version, and that is even with me being someone who typically buys games legit when I want to play them.
