Best battle system (not character buildin) of the main series?

[Formalhaut]

I like the active dimension battle system. Although I think FFXII's take on that type of system can be spoiled by gambit abuse. I personally try to limit gambit use to a necessary basis but the fact that you can abuse this system means that people will, and then become annoyed with the game because it "plays itself". It would have been better if your party leader's gambits deactivate to force interaction.

I like this. If the current Party Leader's gambits are turned off, then it makes things alot less automated. But then you can turn gambits off anyway. While people bemoan the gambit system, you don't have to use it.

I'm very interested in Type-0's battle system. Could someone explain it to me?
