Yea but

Higher block rate= moar block chances = less opportunity to parry....

There are a few threads spread here and there that go into block and parry, etc., etc..

Depends on your build I guess. I parry and block a fair amount, and bulwark is banaynay with Noct, and actually gets used. Bulwark is less effective with some other shields and is used less taking up a slot.

Just my thoughts on it though.

Best way is to get them ALL, and perform your own tests ^^
