PLD Bonus Stats

[Mini-man]

Truthfully emnity isn't really an issue if your maintaining your rotation properly... and if you haven't noticed the itemization on the Melee DOW gear is... the same. Putting it into STR does increase emnity, for Warriors I think it may effect second wind, increases parry mitigation, and for PLD increases the block mitigation, tho the 30 points doesn't add much. For each point of VIT you get about 14.5 HP, multiply that by 30 and you gain approx 435 hp. It'll increase the effectiveness of Stoneskin (10% for cross class and 18% for WHM) and your passive HP regen which is based of off your health pool . Also technically increases the healing from Benediction and Lustrate, and also for WAR will increase the effectiveness of Mercy Stroke (availible for cross class for PLD), Thrill of Battle and Defiance. Realistically its not gonna make a huge difference one way or the other, however for the twinks out there, it appears there is far more synergy associated with stacking it into VIT.

I also wanna note that those extra 435 hp have actually saved my PLD's hide a few times on the Tonberry King with a nasty overstacked Everybody's Grudge and on Titan where at times I've been left with less than 1k hp after a nasty chain of events. Giving yourself and your healer a little extra butter zone is invaluable, esp when the healer needs to let you go for a second to heal up another party member or themselves. That said, WAR has more notable returns for more than just second wind (didnt feel like typing up a story) and thrive off the damage they do so a Warrior will want to consider putting points into STR for the sake of optimization but since this is a post about PLD points... VIT shines bright.

I completely agree with Mini Man.
I don't believe it matters much while leveling, but full VIT is the way to go when you hit 50. I can recall some moments where I suddenly dropped to 200-500 health and it saved the fight. Even having no bonus stats invested in STR, you will never lose enmity if you maintain your rotations. Any points being used on DEX is really not worth it.

You will absolutely want as much HP as you can get to help out your healers when you are on Twintania and she hits you with a Death Sentence + instant Auto Attack.
