Worker 8 and Reis were very useful in my party, especially if you teach Reis White Magic. Cloud was useful in some cases. Orlandu was a freakin powerhouse and made my fights easy(but I'm not complaining )I never used Beowulf, Meliadoul, Mustadio, Agrias, Rafa, and Malek. Plus, I have a separate team that consists of a Ninja, Monk, Black Mage, White Mage, Summoner/Time Mage, and Lancer.
