More advanced battle system please!

What the OP was asking for sounds a lot like version 1.0's original battle system which quite frankly, just didn't work - it played nothing like how a FF game usually is, and came down to spending half your time button mashing the same ability over and over because the stupid stamina gauge that determined damage output just took too long to build up. Replacing it with a battle system that included auto-attack determined by the weapon's speed/delay stat (similar to the system used in FFXI) was one of the first changes Yoshi made upon taking over from Tanaka as producer.

Really, the FF series has always been turn-based combat, even the most recent titles have been to a degree. Only spin-offs and tie-ins like the Dissidia games are the only FF titles to feature more action-based combat. If you're expecting this game to change into an action RPG, then I'm afraid you'll be sadly disappointed.
