Plenty of characters in the Smash franchise aren't fit to be fighters... yet, they find a way. It's called creativity. I would understand that feeling more if the image had him without limbs.
How is he SS Link if he looks nothing like him?
Personally, I would have wanted different incarnations for the characters depending on the system it's on. For example, getting Ocarina or ALBW Link for the 3DS and getting SS Link for the Wii U.
