At present, the official server has entered the end of the Cataclysm version, with many Classic, TBC, and WLK versions available. If you're ready, why don't we just start playing from the CTM version. Now many players like the CTM version, especially Chinese players (because there is no CTM version server in Chinese Mainland, only the WLK version at present) can play without the CTM version. I believe that if you are willing to directly change the original gradual plan and directly open the 85 level content, it will attract many players from Chinese Mainland.
