It was always BS that attack magic was based on INT even if you were a White Mage. It's not like that in any FF game I know, it's always been MND=White Magic damage, INT=Black Magic Damage. I'm glad they changed it. On the other hand, stances are usually a double-edged sword, so I think they could either change the name of Cleric Stance or give it a double-edge. Perhaps increase spell damage but increase MP cost or something. Or increases damage but also slows your cast time or increases your GCD.
