Same here. I loved Final Fantasy 3's class system, then I played 4 and I liked the battle sprites and how cool they looked with their special poses and such then it struck my like an anvil when 5 came out, combining my favorite aspects of 3 and 4 but with a whole new revolutionizing twist on the class system, I loved it. I also loved how you could go out and hunt down the espers for the summoenr class.
This probably leads to another question, I know the classic RPG gives you abilities as you level up, but I was thinking of a new system. Every character has some-type of item (or items for other characters) that teaches them their skills, and the only ones they learn leveling up would be more personal skills and less class based (kinda like the Desperation Attacks/Limit Breaks/Etc.)
What do you think?
