Yep he's referring to the old cure update in either or 03 or 04. It's the one where they lifted the hardcaps on cures. You can add more MND and it would give you slightly more cure amount.

I'm interested to see what happens to BLU magic, it used the Cure V formula just less base cure amount. They said they have no plans to change Blue cure magic, yet I wonder how they go translated to their actual coders.
