remember there are diminishing returns on all defensive ratings (parry/dodge/block). I'm not sure this comes into play on DKs parry, but I'm guessing, given that it exists for all other tanks, that it does. Also genocyde put together what I was trying to say, DKs appear "spikey" when they take damage. Which means I would suck as a MB healer on them, lol. I always wait until 25% to heal!
