There is only 1 thing objectively wrong with the new Varus

And that he uses his right hand to wield the bow...

This is a major overlook and you can't even say that he is ambidextrous because in the video and comic he only uses the right hand. Plus, it's not even a matter of dominant hands, it's a matter of dominant eyes and Varus ingame wields the bow on his left menaing that the dominant eye is his right one (which is the same as Valmar looking at the comic/video).
