To be fair, what about any of his look seems geared toward practicality? The armor has unnecessary weird angles for the sake of looking cool, and since the designers don't have to worry about a real person wearing a real costume, they can do whatever they want for the sake of aesthetics. I'm pretty sure that the surface and texture of the helmet look too opaque and painted to be a full face tinted visor. I guess that's the trouble with trying to design these things before the game is out. It's next to impossible to nail down exact details.
