Sadly i am not good at math like so many of those Theory Crafters out there, But i do love find out which is best for the classes i play. So i go around and look at web pages for info and try my best to look at the numbers when i dps a dummy, or when on a boss fight. Since 2.0, MNK has always been det. ( BiS>acc>Det>Crit.)

3.0 brought us a upgrade to crit. A VERY nice one actually. I have seen the new theory crafted numbers and some others as well for how stats are weighed in 3.0. Crit is only 21 points higher than Det say some of the more well known theory crafters. From what i have understood over the patches in FFXIV. Det is always there. More Det equals out to be more str and more str equals out to be more weapon damage.

I dont not claim that any of this is 100% true. Just info i have picked up through forums and word of mouth. I look forward to hearing others thoughts on this.
