I've taken some time to actually learn the math behind the game, but all the different numbers are spread out everywhere so I'm not sure I'm doing it right. I know there's a bunch of numebrs here, but this is more for my benefit to confirm that I know how the game's math works.
I've done the math and have come up with the following attack table for when a level 83 boss attacks me:
Miss - 11.04%
Dodge - 17.9%
Parry - 14.28%
Block - 17.31%
Crit - 0%
Hit - 39.47%
So the big question is: How's my avoidance balance? Aside from a new weapon and trinkets (along with enchants I haven't put on these new items yet) - am I lacking anything or am I on the right path for Ulduar off-tanking in the near future?
