They only have one weakness and an immunity. Theyre fine. --- Brawl fc: 0946-1910-2716 Pokemon Black 2 fc: 5372-8298-8628 Ruby/Sapphire remakes will be part of 6th gen on 3DS. If not, I'll close my account.
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.
