Accuracy typically isn't a problem. When people mention those high ACC numbers they typically include the ACC bonus from your DEX which is 3 DEX:2 ACC or something like that if I remembr correctly. I usually sit at 360-380 ACC comfortably in most situations. I have even seen MNKs with 350 ACC hit Miser at 100%. Critical attack power is probably more important considering as a MNK you get a forced critical from blindside. I think Crit rate is more of a drg stat if that.
