I quit trying to block cav (I actually quit blocking in general but this has different reasons)
You block one, another comes from behind and bumps you,if you fail to roll, a 3rd one comes and couches you. Fuck this I rather attempt to kill the motherfucker. If i kill, 1 less asshole to deal with, if i die i would just reach the inevitable end sooner .
Try chambering couches and jumpslashing 1handers (assuming you are using manly,short non stabby weapon) Block is overrated, especially against cav.
