The only thing that affect attack in battles is the type ---> Gameplay: Type Matchups

Classes are usually affected by Chracters' special or Captain ability (eg: Double Shooter ATK, Striker HP x1.5 etc..)

Booster are just to exp your characters. Evolver are needed by your characters to evolve to the 2nd or 3rd form. Just check a Character evolution chain to see what i mean.
