There are several programming flaws with FFIV:A. Apart from the multiple bugs (such as characters ATB bars charging twice, guard not working etc), they didn't implement the new ATB system properly. They seemed to only increase the speed of PCs rather than enemies, thus you can get in a hell of a lot more attacks than you could in say, the Chronicles edition. This makes the game ridiculously easy; I was able to get through most random encounters with the attack command and bosses that used to be hard due to timed attacks (Demon Wall, Odin etc) are complete pushovers.

The main flaw with FFVIs battle system is that the evasion stat doesn’t actually do anything. Due to a bug, Evasion is now worked out on Magic Evasion instead. Thus evasion boosting equipment is pointless and darkness doesn’t actually affect game play. So yeah; I will be surprised if they manage to screw up the FFVI battle system more than they already have.
