I've never played FFXII. I heard that in the original FFXII the gameplay was imbalanced and black magic was useless or severly weak once at the mid-end game. Since I like to use magic and magic based jobs heavily it made the game unappealing. However I also heard that in the Zodiac Age remaster the programmers rebalanced the game and made magic of all kinds way more powerful to where is one of the strongest options even end game.

I hope that's true because I'd buy Zodiac Age in a heartbeat if it's system is well balanced.
