Okay, your PLD is only 32, mines 31 so not much difference. I've tank up to Haukke Manor and have no issue with tanking groups.
Tell me why do you think overpower is necessary for you?

Heck, I wish my Warrior's flash has a freaking blind effect on it, not to mention after a few flash and I'm out of MP.
Look at our traits since you have a MRD as well. Does any traits boots or adds effect to overpower?

That's why I don't know why you want more for PLD, especially on the AoE part, which is not that important.
