I could easily beat Orlandu with Ramza 1 on 1 with the right equipment.

If Orlandu has the Excalibur that does indeed present a problem, but with the right reaction skills, equipment and jobs Ramza still comes out on top. Ramza has the potential to easily be the best character, you only need to know how to use him. Without the Excalibur, Orlandu's speed is negligible, Ramza will be able to evade him and keep screaming until he's moving three times to Orlandu's one and his attack or magic power is high enough to defeat Orlandu in one blow. Even if Orlandu does have the Excalibur, you can still make Ramza good enough to evade him and survive long enough to eventually defeat him.
