I already said - there's nothing human in the Charr, right down to their musculoskeletal system. They're a far cry from Mithra, after all.Who, you are arguing, are not humanoid?
Have you ever watched Underworld? I'm sure you've at least heard of it. Did you know that most of the werewolves in the trilogy weren't CGI at all? They used CGI enhancing in some places, but every single werewolf (even the ones crawling on walls/ceilings - they used all sorts of wire acrobatics) were actual people in big old mechanical werewolf suits. They had huge stilt-like legs to stand on, and the head and face had a bunch of animatronic stuff in it. They went all out.
To cosplay a Charr accurately, you'd have to do shit like that. You couldn't just put on a rubber mask and call yourself a Charr.
