2 VIT = 1 DEF
VIT is subtracted from STR in fSTR calculations.
VIT is used as a WS mod sometimes.
VIT is involved in some high tier Cure formulas.
VIT is involved in Waltz formulas.
Those are the current uses. Unless SE patches a bunch of monsters with really high crit rates into the game (which now seems likely) this modification of game formulas really will have no importance at all. The vast majority of the things in the game right now have a ~1% crit rate on me regardless of which level 90 job I'm on.
