I've been workin on this idea since expansion, it seems that for bosses that parrygib expertise cap might be worth it. Overall that tank would take a moderate amount more damage, but they would take a lot less spike damage. I figure going to the hypothetical 15% expertise cap for bosses. I would imagine I would take about 9% less less damage, vs the 12.499% dodge I would gain...... I think I just answered my own question... good job me... but I already typed this all out so might as well post it to see what other people think. Of course, the gear for this is going to be quite hard to get since 65% of the gear has parry or hit for its 3rd stat, and I could finally use reckoning.
