wow, everyone is having great ideas about similar to Final Fantasy Tactic. I wonder if that is the case. I would like to add that if your job or class can advance to more better or different abilities, that reminds me of the MMO called "Rappelz". In this MMO you can advance to more than 1 advance jobs and combine different abilities. I don't know much about the game, but I played once long time ago, you might want to check it out about the job or class system and abilities system.
