Most Useless FF Characters?

[ZoriaRPG]

If you're a fan of the Final Fantasy series (as I am), you are probably aware that in most (if not all) games, there is always at least one character you really don't like as they seem to be useless. For example:

Final Fantasy: The Monk
Final Fantasy IV: Edward
Final Fantasy VI: Gau
Final Fantasy VII: Cait Sith

There are just a few examples from my own experience. What are your opinions?

Emphasis, mine.

You should play them to very high levels. They stop needing equipment, and you put them into bare hands for attacking, where they do more damage than any other class.
