Sure (and I will add this to the review). There are three types of characters: Laughter, Strength, and Knowledge. All of the help characters are of no type, but the battle and support characters fit into one of those categories.

It is like rock-paper-scissors. Power>Knowledge>Laughter>Power. If you are good against the type you are fighting, you will take less damage from them, and you will do more damage to them.

The reason people may complain about balance is that all of the "cool" characters are power characters. Therefore the inexperienced will make an all-power deack. You can see where the problems arise here.
