IF you're a 0 bushido type with 100 parry you will block 30% of melee hits. You'll block 35% with 120 parry.
I don't personally think that the extra 5% is worth it. Against most normally spawning mobs, it just doesn't matter - they generally don't do enough damage in 1 hit to matter, and the battles don't last long enough.
There are a few things that, yes, hit hard, like some of the champs, or doom stuff, or peerless. But melee only mohs are easy. The bigger problem comes from stuff that can cast the beejesus out of you.
Most of the reason that I have any parry is the special move mana cost reduction (I am 0 bush too).
I an in vamp form 100% of the time, and almost always am able to chain AIs. My personal record is 22 consecutive swings that land, and 100% were AIs, with a dmg range of 153 - 201. So for me, landing a hit is infinitely more important than parrying a hit.
