PLD Novus: Parry or DET?

[Fyce]

He's correct. You should max DET. Whether you care to take the time to do it is up to the player. But you should if you have the means. Spirit bond a set of i70 a day and you Kk have enough det IVs in a couple weeks with another 10 mil from selling other materia.

There is not a single encounter in the game where these particular 11 points of Det are mandatory on a PLD and/or would make a noticeable difference on the outcome of the battle.

You really can't justify spending that much time/gils on Tier IV Det for a PLD Relic for such a mediocre increase in DPS.

It's just a matter of OCD satisfaction and theory crafting... which make absolutly no difference in the actual game since it's not built around gear checks at all.
The fact that a single lagspike during the fight can completly nullify the benefits of these stat points is quite enough to say that they are absolutly not worth the invesment.

In theory, they are. In practice, absolutly not.
