practically all normal damaging moves are physical. no special attack love for the normals :P
While I am unsure about whether normal types really need to be Super Effective against something, I do agree that they are in dire need of more widely distributed useful Special moves. Very few of the High Sp. Atk Normals can learn Tri Attack or Hyper Voice.
Edit: Whoops! I Forgot Hyper Voice became a Move Tutor option in this game, and many Normals can learn it.
