This was 2006/2007 I think. Every article I read about it had a different solution and none worked fully.
I also remember when I asked for help on wow centric forums being crappy replies of "don't use Linux" and when I would post on Linux centric spaces getting "don't play wow" replies.
Years ago I made the switch to Linux, then I wanted to play WOW again but it would not run on my Linux machines, so I started to dual boot. Then I began to wonder why I was keeping Linux installed.
Eventually I made the shift to macOS because I worked in theatre and needed it for specific Mac only programs. But I still have a Lenovo legion that I am getting ready to swap over to Linux (not that all of the games I currently play do not run on macOS or my steam deck).
If I was able to get WOW running on Linux years ago I likely never would have swapped back to windows. And I am currently trying to convince my son to install Linux on his pc running windows 10.
I wish I had found you nearly 20 years ago to help me get it running.
