Some of your points make little sense to me. You want to prevent grinding, but you want it significantly harder to build up your stats? That sounds like you would need to grind to find that perfect battle just to raise a single stat.
Actually, I could swear I played the game my first time with very little grinding, but on my most recent playthrough I had to grind more often. I wonder what I did differently...
I actually really like this game and wouldn't mind if Square-Enix revisited this style. I don't see it happening, though, when many people still complain about it.
