fight on flight/bloodbath/scorn/flash/flash/flash/flash it's not so hard, but that's where how strengh can help a pld failling to hold aggro.
because PLD don't have the same aggro than war and dark. i don't think stacking vita is an issue for a PLD if them is very good. but if there an issue, wear 1 ou 2 str accesories would maybe help.
We can't hide the fact when we come to the aggro of the pld
Overpower>flash
Rage of the Halone>the combo aggro of the two other tanks.
The rage of the halone is 260 potency.
But by what you tell, it sound like a pld who don't use flash enough to me
