World of Warcraft has new character models and it is a matter of taste if you like them or not. If you don’t like them, here is how you can disable the new character models in World of Warcraft:

To disable the new models and to let the old models appear, you just need to open the game menu and from there you open the “System” panel and then “Advanced”. On the bottom right you will see a box where you can uncheck the new character models and the old character models will be enabled.

Not sure if this option will be there forever. It could be that Blizzard will force you to use the new models at some point. But at the moment it is an option to get back to the old models. Maybe it will even be an option forever. Who knows? I hope it helped.
