Just as a side note... you don't actually NEED an off tank for Princess. We run PLD WHM BLM DRGx5 (sometimes one MNK) on the princess fight and I (the PLD) have no problem surviving without using Hallowed (I don't have it up anyway since i go WAR for the first rooms). To be clear: I tank both the Princess and the Marshal. And I'm not super built for def/vit either, only 710 and 305 (numbers before protect). I just use DV then Sent once marshal is on me, boon after sent, and... princess is dead. Granted this probably only works in groups with very good DD's, as the longer I stand there the more time I'd spend "naked" without cool downs and probably get eaten.
As to the larger topic of the thread. Dude. Accuracy. Its awesome. Cry more. I rock 182 enmity, and honestly, Curtana will more than make up for the 30 I'd lose in the switch (Garuda/Thoromen's) in just the damage, dps, and spirits boost alone, much less the mp and accuracy.
I would really like to see this addressed by the "wear more str/mnd as PLD" camp, because I've had similar experiences boosting my str from a dismal 229 to 310. As someone else mentioned, I was told that MND pumps Spirits and enmity combo, so I actually maintain 304 Mind and suspect the tank mentioned here has a similar amount (just considering that pieces like HDL gloves and Militia hat give mnd). I'm not saying I don't believe in "DD PLD" i'm just not... entirely sold on the numbers?
