I played it on PS too, Dormos. You're not alone!!

My favorite class was the Time Mage. Not only was Haste the most useful beneficial spell (I found), but when I equipped them with a Hair Ornament (1/2 MP use) and the Lance ability (which any caster should have), they PWNED. Every turn, I used Quick + Meteo + Lance, or if I was feeling especially evil, Quick +Meteo + Meteo.

Sorcerers and Dancers were quite fun too.
