Feh, I have no idea what part of the game you're in, but a lot of the monsters can be beaten down with physical attacks, so my main party always had Sabin, Edgar, and Cyan in it. Sabin's Pummel (or Bum Rush), Edgar's Drill or Chainsaw, and Cyan's Gengi/Offering combo always tear shit up.

The fourth person would either be Gogo or Setzer, depending on what I needed. Coin Toss is a very valuable tool, and so is Mimic.

I have no idea why your attacks are so low. If you're at the end of the game, you should be pulling all nines from all of those people.
