I really loved FFXII's battle system. It still held the same ATB concept of it's more recent predecessors while feeling more "natural." I wouldn't say I had any complaints about being transported to a new location to fight enemies but having them on the same map and being able to move freely around that map during battle had a really nice feel to it. FFXV's action RPG style was very fun too but I like that FFXII could accomplish this while still keeping that Final Fantasy feel.
