I don't DPS much, but am reaching a point where I an afford to add some to my warrior... so I'm curious what stats I should be pumping?

Most tell me Det... but I would think that a Defiance Stanced Warrior would benefit more from Crit, since Wrath stacks add critical hits already at a flat percent, wouldnt you simply be further increasing an innate stat.

Or... would Det be the greater gains,simply because there's considerably less points attributed to it?

Here's where I am currently -

Critical Hit Rate 397
Determination 216

(A note. My current build has been primarily stacking Parry over all other secondary stats)
I'm also not entirely certain how damage stats work compared to FFXI.

I remember in FFXI Damage was something like... Attack increase the Damage Ceiling while Strength increased the Damage floor, or something like that. Can I assume that Strength/Determination work the same way on a graph?
