Only way parry will be remotely useful is if they change it to do a counterattack that does descent enough damage perhaps auto damage while maintaining a decent and realistic proc rate not FF14 RNG flawed system. This would increase MT DPS, actually maybe and honestly mean maybe encourage people to use VIT accessories cause honestly they are a joke too. Right now there is absolutely no reason to stack VIT unless you're a shitty tank or have shitty healers and that's for real any tank buster can be survived with proper cool down usage and minimal HP.
