PLD Gear?

[Judge_Xero]

You should only stack VIT as a PLD if you're trying to survive running through trash mobs (like say, AV).

Otherwise, HP, MND, Accuracy, and STR.

On trash mobs, you would be better to stack Dex (Block Rate) and wear a high Block Rate Shield.
It would be better to block 36% of damage 87% of the time, than 50% of damage 42% of the time.

(Divine Veil @ 100% Block Rate + 75% Block Rate VS. Divine Veil @ 100% Block Rate + 30% Block Rate)

But for your example - AV or CC where your DV timer comes off between rooms and the mob levels are still high you are correct to stack VIT for Block and rely on the 20 second timer for DV

There is a lot of great information on a lot of these posts. Especially the DEF testing (amazing).
It's also a great example of how people interpret a perfectly laid out set of data and testing (seems that some people still don't get it), and also shows the various ways people play PLD.
