I don't mind parry at all. 20% damage decrease for the hit is 20% less damage I take from that hit. Yes, it's deep in RNGesus's buttockal region, but still, it's damage reduction. Though if I had to change it, I'd rather they based more on an actual real life parry. I fence, and if I successfully parry my opponent's attack, their weapon doesn't hit me at all, plus I can immediately riposte. I'd like to see parry in game give you a dodge with say a 15 or 20% chance of an immediate critical counterattack. Failing that, increase the damage reduction to something like 75%.
