I think that is more the issue than the mod itself.
Someone has to be incredibly desperate for character customization to have that be even vaguely playable gameplay wise.
Idk if they hate mods or whatever, but modding in W3 is limited, their modding tools are barebones I remember the work I had just to swap a texture and you can't add anything to the game as an actual new object, you need to overwrite something else.
