Oh.. Man that sucks... I had Gau in my party and I owned him in like 4 hits because he changed his main element or what ever to ice and Gau was casting fire 2 at him.. Then he flipped to fire and thank god Gau used the lance. x x;

I think... Just use Cyan for attacks, Move Sabin to back row and pummel alot, 'cause it should have the same damage, and he'll get hurt less, as for locke... If he has a boomarang or someother backrow weapon, give that too him and move him in the back row, and if anything use him as the own to give out potions and such. .. I dunno though..
Since Gau owns everything in my game. <3.
