Hello there,
I understand that some players preferred the old models and I appreciate you taking the time to share your feedback. However, rolling back to the old models unfortunately isn't possible. Adding the old models as an optional setting also isn't something I can realistically support, since maintaining two separate model pipelines would significantly increase development time and scope.
I understand that this change may not work for everyone, and I'm sorry to hear it affected your enjoyment of the game. At the moment the only alternative would be through mods created by the community.
