still dose not matter how much damage parry absorbs if you cant even moderatly predict or control when you parry. Pary vs Block is not only a moot subject but if you wanted to compair the two, block wins on several fronts

1) hands down, block happens more offten even w/o devine veil

2) If you know how to play pld, all i have to say is "devine veil" and thats enough said

3) both 1 and 2 aside ageious boon blows parry out of the water, that ability alone alows you to not only block 100% of the damage from an attack, you can purposly time it for when you need it, it gives HP back and just using that ability as often as you can puts your block rate WAY above your parry rate.

not hard to see BLOCK > PARRY K.O. first round knock out.
