I agree that a fourth character would make the game too easy. I also think that an archer wouldn't be really necessary, since we already have Lance, who has a ranged attack of most if not all elements.
Switching out players might be a good idea; maybe you would need her to complete a certain stage or something.
Keep up the good work! Loved EBF3
