If Block chance is being affected by Parry, couldn't you just take off a ton of crit gear and see your block chance increase? I do not see that happening on live. If I recall correctly, Parry has a footnote stating that the number displayed is "before diminishing returns". No clue why they would do half with DR and the other half without. Also, I think one of our hidden passives gives us a 50% multiplicative to our block chance. Why have something like that in the game if you will also have an incredibly harsh DR to block as well.
